Set temporary cache locations of dependencies from one location

[d33bs]

At the moment, temporary cache locations may be specified for cloudpathlib use in CytoTable by using the cytotable.convert(..., local_cache_dir='',...) local_cache_dir parameter (via **kwargs). sqlite3 includes an additional cache layer which is sometimes used for mixed data type column translation which is specified through environment variables (see here) or a PRAGMA command (see here). It might be possible to explicitly set these to the same location for simplicity, or to set them from the individual queries for SQLite somehow.
