Memory map:
- Change to a 5x5 display
- Remove pointer to keypad (I can't see why you would want to relocate it)
- Add placeholder for bank-switching flag
- Remove `$30` as initial value of IP - that's covered (differently) by the new CPU start-up section

! Refactor (assembler): Chance constant prefix from '=' to '#'

'=' could be confusing when referencing a constant, since it looks like assignment
'#' is hopefully clearer (by analog to #hashtags)
