ENH: Utilize q2-vizard for visualisations of TIC, BCP and retention time correction

[VinzentRisch]

For a TIC, BPC or retention time correction visualisation the visualiser line-plot can be used.
For this the files in the XCMSExperiment have to be converted into a Metadata table.
This could be done as an action, a transformer or a pipeline that combines the action and the visualiser.
