FUNCTION fHtmCoverCircleEq

Returns the HTM Cover of a circle with a given ra,dec and radius

Returns a table of htmid ranges describing an HTM cover for a circle centered at J2000 ra,dec (in degrees) within @radius arcminutes of that centerpoint.
Parameters:

@ra float, J2000 right ascension in degrees
@dec float, J2000 declination in degrees
@radius float, radius in arcminutes
returns trixel table(HtmIDStart bigint, HtmIDEnd bigint)
