Concat bug with mikeio>2.0

[daniel-caichac-DHI]

Hi,

I think there is an issue with generic.concat and dfs0 files at least.
The documentation of generic.concat says that it should work with keep either first or last

But the documentation of _dataset.py says that it only works with last

Well, I am using generic.concat, and instead of calling generic.concat, it is going to dataset.concat apparently

• Just tried with mikeio 2.0.0 and 2.0.1, same conclusion.

• I downgraded to 1.7.1 and same script now works fine

Thx for reporting this, the reason for this was that concatenating dfs0 files looping over every timestep is a bit slow. But I missed the fact that only one keep option was available.
