Added a start address (equivalent to main) to assembler
...
Creates a jump address to the label delegated by "global" so program
starts at that point.

Made separate tokens for JUMP_ABS and JUMP_STACK
...
Makes more sense, don't need to fiddle around with strings as much in
the parser due to this!

Lexer now returns more descriptive tokens
...
More useful tokens, in particular for each opcode possible. This
makes parsing a simpler task to reason as now we're just checking
against an enum rather than doing a string check in linear time.
It makes more sense to do this at the tokeniser as the local data from
the buffer will be in the cache most likely as the buffer is
contiguously allocated. While it will always be slow to do linear
time checks on strings, when doing it at the parser we're having to
check strings that may be allocated in a variety of different places.
This means caching becomes a harder task, but with this approach we're
less likely to have cache misses as long as the buffer stays there.

Lexer now returns errors on failure
...
Currently only for invalid character literals, but still a possible
problem.

...
Accurate error reporting can be introduced using this.
