Change Depends to R >= 4.1

[krz]

I was unable to install this package on my R 4.0.4 machine and tracked the issue down to line 424 in generics.R file:
try_result <- tryCatch(subset <- rep_len(TRUE, dim(result)[length(dim(result))]), error = \(e) e)

\(e) e is a new anonymous function introduced in R 4.1, so either the Depends requirements in DESCRIPTION should be updated or the usage of this new syntax should be avoided (for now).
I would opt for changing to old-style functions as 4.1 is still relatively new.

Thanks for pointing that out. I've changed it back to use the old syntax, but will have to test that it works on R 4.0 more comprehensively.

thanks, installation from github now works for me.
