Implement functions
...
- Implement function declaration and call
- Change the precalculated variable stack positions to contain the
offset from the end instead of the absolute position. This is
important for passing fun args on the stack
- Add the ability to offset the stackframes. This is used to delete the
stack where the fun args have been stored before the block executes
- Implement exit type for blocks in interpreter. This is used to get the
return values and propagate them where needed
- Add recursive fibonacci examples

Remove panics from interpreter, worse performance
...
- Replaced the interpreters panics with actual errors and results
- Added a few extra checks for arrays and div-by-zero
- These changes significantly reduced runtime performance, even without
the extra checks

Rewrite declaration as statement instead of binop
...
- Declarations are now separate statements
- Generate unknown var errors when vars are not declared
- Replace Peekable by new custom PutBackIter type that allows for
unlimited putback and therefore look-ahead

Big token refactoring
...
- Extract keywords, literals and combo tokens into separate sub-enums
- Add a macro for quickly generating all tokens including the sub-enum
tokens. This also takes less chars to write

Implement vec based scopes
...
- Replaced vartable hashmap with vec
- Use linear search in reverse to find the variables by name
- This is really fast with a small number of variables but tanks fast
with more vars due to O(n) lookup times
- Implemented scopes by dropping all elements from the vartable at the
end of a scope
