sp_BlitzIndex: columnstore compression details, include dictionary sizes

[BrentOzar]

Is your feature request related to a problem? Please describe.
I'm working on a course, and I want to show compression details from sys.dm_db_column_store_row_group_physical_stats.

Describe the solution you'd like
In the table-level columnstore visualization, for each rowgroup, show the state_desc, trim_reason_desc, transition_to_compressed_state_desc, and has_vertipaq_optimization columns.

Describe alternatives you've considered
Writing a separate visualization script.

Are you ready to build the code for the feature?
Yep! Coded.

Added feature while I'm in there: in the past, the columnstore visualization section didn't include the secondary dictionary sizes for each segment, only the segment size itself. Since I'm poking around in internals, it's relatively easy to include the secondary dictionary (but not the global, since it isn't repeated).

Users table, before - note the sizes in the DisplayName column at far right:

After, including the secondary dictionary sizes:
