Documentation for new API/CLI needed

[jbbrownlsi]

The main README does not yet simply explain any of the October 2025 additions (BILNParser and pyPept-cli-validateSequence).
It needs to be updated.

Also, the version number should increase from 1.0 to 1.1 , as this update update represents a significant step forward from the 1.0 release in 2023.

Partially addressed with several new notes in the first section(s) of the README.
Still, more documentation would improve awareness of the additional functionality.
