Develop else

[rburghol]

@PaulDudaRESPEC
This PR fixes a bug in the special actions code whereby the ELSE statement is not caught and parsed, resulting in an error. Notes:

• It does not yet add correct IF-THEN-ELSE support (that is coming very very soon).
• Ir does allow a UCI to have structures containing an ELSE and not fail.
• This is also a test to see how the automated testing goes for this (last PR was 3 months ago and testing results no longer are available).
  • It appears that recent updates to h5 library code cause hsp2 import_uci ... calls to fail due to a redundant call to open the h5 file.
  • This error throws in python 3.9, but does not appear in python 3.12 as of this PR. This is mentioned in a comment to HSPsquared model created from ./tests/land_spec/hwmA51800.uci fails with KeyError #180 (they are maybe related as one throws a KeyError and the other a ValueError). @timcera
  • Note: Automated testing of python 3.9 completes both hsp2 import_uci ... and hsp2 run ..., so this may be a problem with my local install/lib setup? I will report back here.
