Make contact tag a CVParamGroup

Need to make the contag tag a CVParam group to make it more extensible,
so that people could add additional information about contacts by
referencing a different CV, and including a new mapping.
Software element extends CVTermType

Changed it from ParamGroupType so that only the name
of the software is recorded. The version of the software is recorded in
the attributes.
Add element to name decoupling method.

Rename TimeDomain to a more clear name

Remove dwell time

Dwell time is not needed because we already capture sweep width
and dwell time = 1 / sweep width

It should be added to reference API implementations calculated from
the sweep width.

NOTE Bruker sweep width and dwell time may be different.
