Script changes to support Google Fi lab tests

TelLabProjectFiTest.py -- Modified the TelLiveProjectFiTest.py
from Tel/Live and created a new script in the Tel/Lab to support
the Lab callbox testing.

md8475a.py / anrtisu_utils.py - Has changes to support Google Fi
SIM profiles for TMO / SPR & USCC.

TelLabCmasTest.py / TelLabEtwsTest.py  -- Added methods to
change the SIM profiles between TMO / SPR & USCC.

Bug: 127582302
Test: Locally tested the scripts with the callbox. Ran the scripts to
switch the  profile to TMO > ran CMAS / ETWS tests > switched to
SPR / USCC > ran the CMAS / ETWS tests again.
