Add ability to pull out statistics based on format/content type

[gamontoya]

Descriptive summary

Currently DAMS Manager gives administrators the ability to pull out collection statistics based on collections.

• https://library.ucsd.edu/damsmanager/collectionsReport.do

We also expose stats based on format type in DC:

https://library.ucsd.edu/dc/search/facet/object_type_sim?facet.sort=index

Perhaps it would be best to use the query used by DC but add a new column for total size in GB and also give the user the option to include or exclude objects that are curator-only, UCSD IP restricted, or by unit only (DLP vs RDCP).

Rationale

We need the ability to pull out statistics based on format/content type (audio, video, text, etc.) for statistics reporting to outside agencies.
