Proposal: paste0 lint

[jonocarroll]

paste(..., sep = "", collapse) -> paste0(..., collapse).

I am not quite sure what the impact of ... is here in terms of how jarl extracts arguments, but perhaps this is addressed in examples already.

It's a good idea, this is also listed in #8 (paste_linter). I suggest taking a look at lintr test suite, if I remember correctly there are several corner cases.

For dots, you can take a look at how get_unnamed_args() and drop_arg_by_name_or_position() are used in other rules.
