DataProfiler.Data should use relative path, then fail over to absolute

[lettergram]

Is your feature request related to a problem? Please describe.

I should be able to use relative path when doing dp.Data(/file/is/here/data.csv)

Describe the outcome you'd like:

I think it's fine to use the absolute path, but the relative path would be more intuitive.

Additional context:

@lettergram does relative path work when you drop the / at the beginning of the passed in file path?

@lettergram any update?
