Tokens.
This module handles descriptions of all tokens that can be found in an AML byte stream, storing them and their properties.
The token type ends up, in most cases, being the smallest most fundamental type used in the parser (as in the type at the bottom of the recursive tree), but there are some exceptions, for example a ByteData object is not a token type simply because it can have any value (0x00 to 0xFF).
| enum aml_encoding_group_t |
| enum aml_token_num_t |
Token numbers.
All tokens stored an an enum, we also encode the extended tokens (those that make up two bytes) by assigning them certain token ranges.
| enum aml_token_type_t |
Token Type.
