João v2.2

New year, new João.

Optimizations 🥇

João now does some basic constant folding of operations between literals. (1 + 2) will now properly be parsed as 3 before the code is run by the interpreter.
Hashtables now grow in a slightly more optimized way. Scripts with heavy table load should be 5 - 15% faster.

log10() and log() were added to the math library.
The new keyword continue was finally added, behaving similarly to how it does in other languages.
In Safe Mode, HashTables in the language are now not allowed to use more than 512 MB of memory, each.
/explode() now accepts strings which are not singular characters, as well as empty-string separators (which results in the haystack being returned as the single element of the returned table).
Another new keyword is const, which, when given a block, runs itself before the greater program is run and is replaced with its return value. This is similar to C++'s constexpr, except in our case, it has the full functionality of João at its disposal.
Interactive Mode now functions in a manner more akin to a scientific calculator, with the evaluation of expressions. A full REPL implementation will appear in the next patch.
João now supports being compiled in an Emscripten WASM environment. Read the new documentation on the matter for more.
The Documentation now describes how to compile João, plus some reference information on the math library.

Fixed Joao emitting #error directives when compiled on certain Clang builds.
Fixed instantiating /error with the wrong arguments causing a read access violation.
Constructors now properly halt and return null if there is a runtime when evaluating their arguments.
Fixed large breaks in complicated situations not always working correctly.
Fixed incorrect error message when the parser fails to find a missing closing parenthesis.
Fixed occasionally-incorrect parsing of expressions of the form arr[x()] or similar.
Fixed parser errors at keyword tokens not informing you of what keyword it's confused about.
Fixed all Interactive Mode statements occurring only as statements within /main().
Fixed indirect access of methods and functions not working (doing /foo() instead of foo(), etc)
Fixed several math functions not checking the number of arguments given before trying to access them.
Fixed expressions like .1234 not being valid numbers.
