Modify peak picking parameters to call by relative abundance (not absolute value)

[kheal]

Will change in lcmsrefactor branch.

Current peak picking parameters for LCMSBase class for minimum height and persistence are set as absolute values. In order to better parameterize these settings and follow conventions in CoreMS, we should change this to use a parameter like relative abundance for setting minimums.

As currently implemented, that is how we set our values, so functionally it will not change, just the parameter names will change.

Implemented on lcmsrefactor_heal branch.
