Updated the demo, realized anonymous scopes don't work right :(

I made it so starting a named scope serves the dual purpose of creating a symbolic reference to the current PC

This is s a big rewrite including: A scoped symbol table, segment and
...
bank management, Use of promises to resolve symbols that are used before
they are defined. A base class for all instructions and assembler
directives. Hopefully my scoped symbols can be used to create C like
data structures in the zero page, ie sprite.x New code to prodce the
final ROM. Basically everything was rewritten.

Trying to re-organize my classes, and add a base class for objects which can emit_bytes to the ROM

Trying to make the demo asm a bit nicer, before moving onto treetop parser

Some updates but assemblying programs with multiple banks, or more prog and char sections is messed up

Ported NES101 tutor to this assembler, fixed the PROG and CHR positioning in the ROM, added more directives .ascii etc.

Accidentally had the opcode for TXA be NOP, don't know how that happened. I ported background.asm from NESASM format to my format, it is veeeery similar so not much needed changing, and the resulting ROM worked fine :)

I have added many directives, such as .org, ines header, .dw, .bytes, and made it produce proper Roms launch into the entry point at 0xC000 from the reset vector. I basically rewrote the Assembler class, this could still use some cleaning up though, more unit tests, and to compile some code with CHR segments
