Add support for table prealloc syntax

[Zjonn]

Closes #7

Brief

I've implemented support for table prealocation syntax.
New grammar allows to produce

• table = {&A &B}
• table = {&A}

@Askaholic please take a look

Thanks for the ping, for some reason I wasn’t watching this repo so I didn’t see that the PR was opened. I’ll review this properly as soon as I can.

In the mean time do you have any idea if your implementation is similar to that of the GPG one in actual FA? When possible I’ve been trying to keep the implementations close to existing stuff that can be observed in the FA exe. There’s only so much you can do but sometimes it’s possible to tell more or less how the call tree looks and try to mimic that in this codebase.

In the mean time do you have any idea if your implementation is similar to that of the GPG one in actual FA? - no, not really, I just saw that the fa repo tests were failing on this new syntax and I decided to fix it.

I've implemented it in simplest possible way, so from a call tree prepective

table1 = {&A &B}
table2 = {}

should be equal. In addition A, B can only be numeric tokens, so I could assign them directly to ConsControl.
