Add m/z shift option

[ajmaurais]

New params.msconvert.mz_shift_ppm option

• Add an option in MSCONVERT to shift all m/z values in mzML file by by n ppm. This is a useful option if the mass calibration of the files have to be adjusted.
• Because there is an additional msconvert parameter the path of the storeDir was also adjusted to avoid collisions between different combinations of parameters.
• Instead of using a new sub-directory for each parameter the storeDir path is now based off a hash combining the string of the msconvert command and the proteowizard docker container. There will be a unique storeDir path for each combination of msconvert parameters and versions of the proteowizard docker container.

Bug fix

• Add a flag in SKYLINE_RUN_REPORTS to override existing reports in the template document if they conflict with the names of new reports being added in the .skyr file. Without the --report-conflict-resolution=overwrite option, if someone were using a custom template document and the report names conflict they will get an error.
