Driver bugfixes [Needs testing Keysight 34465 and Triton 450]

[thangleiter]

These are three small bugfixes on different drivers.

• The DecaDAC range did not include the highest bit
• Our Keysight 34465 model returns a firmware version string incompatible with convert_legacy_version_to_supported_version, so it's chopped.
• The current section parsing did not work with our Triton 450. Replaced by a regex.

It would be great if someone could verify the last two changes work on someone else's instruments.

@thangleiter Thanks for the contribution. I don't have access to test these but they seems sensible to me. Could you add a newsfragment as descripted in the pull request template. You will also need to run the precommit hooks to fix small formatting issues.

@thangleiter FYI you don't need to worry about merging main into the branch. We will automatically test against latest main when merging

@thangleiter I changed the title to try to ask for testing a bit more clear. I will leave it for a few days before merging
