// Lookup table to map the previous two bytes to a context id.
//
// There are four different context modeling modes defined here:
// CONTEXT_LSB6: context id is the least significant 6 bits of the last byte,
// CONTEXT_MSB6: context id is the most significant 6 bits of the last byte,
// CONTEXT_UTF8: second-order context model tuned for UTF8-encoded text,
// CONTEXT_SIGNED: second-order context model tuned for signed integers.
//
// The context id for the UTF8 context model is calculated as follows. If p1
// and p2 are the previous two bytes, we calculate the context as
//
// context = kContextLookup[p1] | kContextLookup[p2 + 256].
//
// If the previous two bytes are ASCII characters (i.e. < 128), this will be
// equivalent to
//
// context = 4 * context1(p1) + context2(p2),
//
// where context1 is based on the previous byte in the following way:
//
// 0  : non-ASCII control
// 1  : \t, \n, \r
// 2  : space
// 3  : other punctuation
// 4  : " '
// 5  : %
// 6  : ( < [ {
// 7  : ) > ] }
// 8  : , ; :
// 9  : .
// 10 : =
// 11 : number
// 12 : upper-case vowel
// 13 : upper-case consonant
// 14 : lower-case vowel
// 15 : lower-case consonant
//
// and context2 is based on the second last byte:
//
// 0 : control, space
// 1 : punctuation
// 2 : upper-case letter, number
// 3 : lower-case letter
//
// If the last byte is ASCII, and the second last byte is not (in a valid UTF8
// stream it will be a continuation byte, value between 128 and 191), the
// context is the same as if the second last byte was an ASCII control or space.
//
// If the last byte is a UTF8 lead byte (value >= 192), then the next byte will
// be a continuation byte and the context id is 2 or 3 depending on the LSB of
// the last byte and to a lesser extent on the second last byte if it is ASCII.
//
// If the last byte is a UTF8 continuation byte, the second last byte can be:
// - continuation byte: the next byte is probably ASCII or lead byte (assuming
// 4-byte UTF8 characters are rare) and the context id is 0 or 1.
// - lead byte (192 - 207): next byte is ASCII or lead byte, context is 0 or 1
// - lead byte (208 - 255): next byte is continuation byte, context is 2 or 3
//
// The possible value combinations of the previous two bytes, the range of
// context ids and the type of the next byte is summarized in the table below:
//
// |--------\-----------------------------------------------------------------|
// |         \                         Last byte                              |
// | Second   \---------------------------------------------------------------|
// | last byte \    ASCII            |   cont. byte        |   lead byte      |
// |            \   (0-127)          |   (128-191)         |   (192-)         |
// |=============|===================|=====================|==================|
// |  ASCII      | next: ASCII/lead  |  not valid          |  next: cont.     |
// |  (0-127)    | context: 4 - 63   |                     |  context: 2 - 3  |
// |-------------|-------------------|---------------------|------------------|
// |  cont. byte | next: ASCII/lead  |  next: ASCII/lead   |  next: cont.     |
// |  (128-191)  | context: 4 - 63   |  context: 0 - 1     |  context: 2 - 3  |
// |-------------|-------------------|---------------------|------------------|
// |  lead byte  | not valid         |  next: ASCII/lead   |  not valid       |
// |  (192-207)  |                   |  context: 0 - 1     |                  |
// |-------------|-------------------|---------------------|------------------|
// |  lead byte  | not valid         |  next: cont.        |  not valid       |
// |  (208-)     |                   |  context: 2 - 3     |                  |
// |-------------|-------------------|---------------------|------------------|
//
// The context id for the signed context mode is calculated as:
//
// context = (kContextLookup[512 + p1] << 3) | kContextLookup[512 + p2].
//
// For any context modeling modes, the context ids can be calculated by |-ing
// together two lookups from one table using context model dependent offsets:
//
// context = kContextLookup[offset1 + p1] | kContextLookup[offset2 + p2].
//
// where offset1 and offset2 are dependent on the context mode.
