v1.3.0

[1.3.0] - 2025-01-01

Added

• Optimisation i for simplifying IF statements when a variable is checked against non-zero value that can be reduced
  to the variable itself. (Thanks to Valentino "SVS" Zenari for the idea.)

Changed

• Literal labels are ordered by name instead of value in label list dump.

Fixed

• Missing file and line info from pre-processing directive error.
• Line joining when previous line finished with an END command.
• Changed order of source processing steps. Previous version completed code optimisation before pre-processing and
  produced less optimal code. In this version pre-processing is completed before optimisation then line number
  assignment. This way line joining and other optimisations are producing better outcome.
• Line joining to also join following lines to a line with line label at the beginning.
• Line joining to ignore strings in double quotes when assessing whether the line could be joined with others.
