CamStats Output is not valid PVL - Parsing issues

[jlaura]

ISIS version(s) affected: all

Description

See this issue opened on the PVL library. Effectively, having a quoted "User Parameters" aggregation block name in the camstatsoutput is not allowable by the PVL specification. Therefore,camstats` output is not valid PVL meaning other libraries can not parse it.

How to reproduce

Run camstats and then pvl.load using some recent version of the PVL library.

Possible Solution

How about UserParameters, no quotes, no space.

Additional context

We will work around this for releasing Voyager ARD. In the long term, this makes camstats output essentially unusable for ARD generation without additional code infrastructure to correct the problem.
