build command fails on bitwise and

[vincent-io]

Pico-8 version 0.2.0 introduced the & operator to do bitwise and (deprecating https://pico-8.fandom.com/wiki/Band), but this is not supported by picotool:

Traceback (most recent call last):

Same thing for | (bor, same error), ^^ (xor), << (shl), >> (shr), >>> (lshr), <<> (rotl), >>< (rotr). | has the same error as &, the others trigger

pico8.lua.parser.ParserError: exp2 in binop

[hsandt]

Not sure why, but adding b'&', b'|', b'^^', b'<<', b'>>', b'>>>', b'<<>', b'>><' in BINOP_PATS in parser.lua is not enough, now I get:

... File ".../picotool/pico8/lua/parser.py", line 719, in _exp return self._exp_binop(exp_term) File ".../picotool/pico8/lua/parser.py", line 751, in _exp_binop exp_second = self._assert(self._exp_term(), 'exp2 in binop') File ".../picotool/pico8/lua/parser.py", line 339, in _assert raise ParserError(desc, token=self._peek()) pico8.lua.parser.ParserError: exp2 in binop at line 117 char 24

I added the binary operators in 54b84fe74b95c98a562822b2c42f6b3e9f4c0690. (Your change may not have worked because the lexer patterns are ordering sensitive, e.g. >>> has to come before >>.)

I added the unary operators in dd7b9b40ec5f7598cc36d009f30286aa0b0d575a.
