Add function for DBSCAN clustering algorithm

Description

The DBSCAN clustering algorithm (​https://en.wikipedia.org/wiki/DBSCAN) seems to receive a good bit of attention in literature and practice; having a PostGIS implementation would be nice.

The existing clustering functions are in fact a special case of DBSCAN, with minPoints = 1, so this addition would complement existing capabilities nicely.

Isn't this something that should be implemented at the PostgreSQL side ? ​https://wiki.postgresql.org/wiki/TABLESAMPLE_Implementation
