Fix Chirp Correlator and Cal Type in Raw, NET, RSLC EAP and NEB

[rad-eng-59]

This PR is the merged combination of the two exiting PR #192 and PR #211 plus some minor improvements.
The main reason for the merge is that these two older PRs are fixing mainly the the same underlying issue with telemetry but for two different applications. Besides, this avoids merging conflict in future while placing the respective common helper functions under appropriate namespaces at once. Thus, once this PR is reviewed and ready to merge, those two older PRs can be safely removed.

Here is the summary of key updates:

1. Improve Raw parser with helper functions to parse chirp correlator and cal type properly by adding a support for cross-pol products as well as full polarimetric products for Quad-pol case that is currently wrong or missing.
2. Add a new module to compute residual RX channel imbalances, detect anomalies in received echoes (aka sample slip) where they are used as part of EAP in RSLC.
3. Update antenna pattern module to use frequency band and caltone for proper synthesis of RX DBF pattern. This requires caltone frequency parser incorporated in Raw L0B parser.
4. Update noise estimator module (NET) to handle QP properly with correct chirp correlator and cal type values. Also fix some potential biases in noise estimation due to dynamic CPI size in default MEE approach.
5. Update python API for noise estimator module used in RSLC to estimate NEB. The update adds support for QP w/ correct chirp correlator and cal type telemetry info and force CPI to stay as close as to the input value (or its maximum) for more robust noise power estimation across swath.
