[evlatests] new executor software (v1.2.1)

[Rich Moeser]

A new version of the Executor has been released.

Fixes (per Barry and Ken): 

1. 4Band setup
2. Planet numerical problem, and others
3. Correlator setup handling
4. "Can't change correlator setup on successive scans" bug.
(I know, the last bug was already fixed a while ago.  Well, it came unfixed.)
5. P band/FE filter bandpass mismatch at some P band frequencies.
