Title: Make repeating groups readable and writable

Although Stirling has had support for parsing (and, in principle, formatting) repeating groups for a long time, neither getting nor setting field values within a repeating group has been possible.

Add `FieldContainer#getGroup` that provides access to a repeating group identified by the tag giving the number of repeating group instances, such as NoLegs(555) in FIX 4.3.
