This commit implements an LL(1) lexer and the parser for the JSON specification. Both the lexer and the parser are integrated in the same structure for the sake of simplicity. There is no buffering of tokens. Any token produced by the lexer is immediately consumed by the parser. In fact, the parser triggers the lexer to create a token only when it requires one.

The destructor recursively traverses the object tree releasing memory accordingly. Since, key-value pairs are stored in a hash map, the key needs to persist longer than the lifetime of a token, which is where we derive the key from. As of now, tokens are not freed. In the future, we need to implement a recyclable token that is destroyed along with the parser. Removed the `TokenChannel` enumeration because the tokens are always generated on the default channel, given we don't generate tokens for whitespace.
