Put axis labels in WCPS queries.

Note that for v9 rasdaman the band names need changing as well so
doesn't work yet.
Fix rgb range subsetting to be v9 compatible.

From maybe v9.0.3 or a bit before we can't use c.red/green/blue
to get these bands of coverage (unless explicitly set in petascope
from v9.0.3?) so used .0/1/2 in WCPS alpha query and for the single
image WCPS queries on an rgb coverage simplified the queries
considerably but just taking the whole coverage and not building
up the bands individually.
Make example_BGS.html use BGS v9 services.

Show setting of axis labels required with some notes on v8/v9
changes.

Solved conflicts by incorporating my changed queries with
axis labels into the new blocks created by test for colorOnly
