Generate report can be called through mp run as an optional argument

[andrsbtrg]

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

As a user I would like to pass an optional parameter to mp.run to specify when I want to create a report

Describe the solution you'd like

Something like

mp.run(spec_a, spec_b, report=True, r_path="./reports/")

Describe alternatives you've considered

There is already a public method to specify a report but it has to be called after mp.run, which can cause confusion.

For example, this would not work:

mp.generate_report('./reports/')
mp.run(...)

But this works:

mp.run(...)
mp.generate_report('./reports/')
