This allows mixed-case in both PETSCII Upper/Lower and
ISO encodings, as all printable characters in strings are
preserved as-is.

(In PETSCII Upper/Graphics, you can use the graphics
characters on the shifted letters in names, but they will
be ugly, and they won't be distinct from the unshifted
version. That is, LABEL=label=Label=lABEL=whatever glyphs
that would be in PETSCII.)

The assembler is now case-insensitive on input, folding all input to a single case, except inside quoted strings (.BYT directives). Labels may now contain lowercase characters, but they are case-insensitive. This allows mixed-case in both PETSCII Upper/Lower and ISO encodings, as all printable characters in strings are preserved as-is. (In PETSCII Upper/Graphics, you can _use_ the graphics characters on the shifted letters in names, but they will be ugly, and they won't be distinct from the unshifted version. That is, LABEL=label=Label=lABEL=whatever glyphs that would be in PETSCII.)
