Feature-completeness (but for real)

• Make all segments optional
• Add custom @ICONS syntax
• Change permute-shorthand operator to * instead of :
• Bugfixes out the ears

Feature-completeness

• Support multiply-symmetric tabels (i.e. allow changing symmetries: directive midway through)
• Implement permute shorthand (using state:count rather than compass directions)
• Implement both formerly-tentative output-mapping forms
• Expand transition-searching to take symmetries into account
• Various bugfixes
• Change name back to rueltabel

Rename to rueltable

^ That's the biggest change, but this release also implements the old "tentative" PTCD syntax (copying a neighbor state) as well as negation+subtraction of variables

It (actually) works

Fewer bugs than last time!!
The TODOs from previous release still apply, but I can at least truly say that it "works" now. Or at least that it's reasonably likely to.

It works

TODO:

• Support Python versions below 3.6
• Do unit tests
• Preserve comments in compiled output
• Fix SO many bugs

...but it works!
