Add function to enable resampling to 10 minutes

[Sachagobeyn]

The input data for computing the R-factor should be equal to 10 minutes as this is the resolution on which the formula's are based. A resampling methodology for timeseries with another resolution is added. This can be used by users to resample. The workflow is as follows:

• The input rainfall data should always have a 10-minute resolution as formula's are developed on that scale.
• Run rfactor, and if input data are not 10 minute resolution, throw warning (or error), and suggest resampling function TO DO
• Apply resample: first resample to 1 minute (with bfill) and then resample to 10 minutes (sum), do not allow non-constant frequencies and do not allow sub-minute frequencies.
• Rerun rfactor with resampled data

To do:

• [x] Check docs
• [x] Check application decorator
• [x] Check precommit
• [x] Validate decorator
• [ ] Add tutorial to tutorial page

@johanvdw , @stijnvanhoey : do you have any idea why https://github.com/cn-ws/rfactor/runs/6160368522?check_suite_focus=true pops up?

@stijnvanhoey : I implemented a decorator function to check rainfall input data (with input parameters for the decorator function with the itertool wraps function). Yet, this reminds me of https://github.com/keleshev/schema, do you think it is it applicable here?

To solve this, switch the git://github... into https://github... in the pre-commit configuration on line 4 https://github.com/cn-ws/rfactor/blob/master/.pre-commit-config.yaml#L4

@stijnvanhoey : thanks for the comments, valid.py is a new script + test files added + docs on how to use resampling function is also provided. I'll merge when drone is finished.
