Removed deprecated gwpy.table modules
This PR introduces a backwards-incompatible removal of multiple modules/functions related to augmenting the glue.ligolw
table objects with useful functionality. The removed modules are
gwpy.table.lsctables
gwpy.table.utils
gwpy.table.rec
gwpy.table.rate
gwpy.table.io.ascii
Basically this removes all functionality associated with importing ligolw lsctables
objects from gwpy, and the unified I/O that used to be attached to them, e.g. you can no longer do anything like
>>> from gwpy.table.lsctables import SnglBurstTable
>>> t = SnglBurstTable.read(f)
instead you should do something like
>>> from gwpy.table import EventTable
>>> t = EventTable.read(f, format='ligolw.sngl_burst')
