Impact.select() reset_frequency option

[timschmi95]

Currently, Hazard.select() has a reset_frequency option, but Impact.select() doesn't.
I have the use case of having an impact object which is not created through ImpactCalc (i.e. not from any hazard object) and need to select a subsample (e.g. only the last 10 years). In order to get the correct exceedance frequency curve, I need to manually adjust the frequency of the new impact object after the selection.
Do you think this is a common enough use case to add a reset_frequency option to impact.select(), equivalent to hazard.select()?

I think this is reasonable yes.

Not at the moment, but I should be able to provide a pull request within the next one/two months.
