Enrich parquet export by joining with more tables

[hombit]

PR #29 implements a very naive approach to the light curve export and just joins diaobject with diasource and diaforcedsource. It should also add more information like isdect, host galaxy properties, redshifts, etc.

One of the ways of implementing it is creating a permanent view which would be dumped to parquet, maybe with a few WHERE statements for filtering by provenance. See also #47

...given that these queries are slow, we should also implement a submit job, check if done, get results loop (similar to the whole long query runner thing).
