Lengthen analysis period and max loan term variables

Pull Request Template

Description

Change ssc vartable limits to allow analysis periods of up to 100 years.

Fixes # NatLabRockies/SAM#2140

The SAM GUI has several seconds of "not responding" when attempting to shorten a long analysis period, but this also occurs on the released version (say changing 50 to 45) so I haven't attempted to address it here.

Corresponding branches and PRs:

Develop of wex, lk, sam-private

SAM PR NatLabRockies/SAM#2139 resolves some related callback issues that make this easier to test, but these are technically independent.

Unit Test Impact:

Open to suggestions on unit test impact
