Feature Request: Add `$TEXMFHOME/bibtool/.bibtoolrsc` to default resource paths

[lorenzleutgeb]

I am aware of multiple ways to configure resource file paths, such as -r, -R, resource.search.path and that there are default paths such as ~/.bibtoolrsc{,.rsc} being searched.

I would like to propose an addition to the list of default search paths, namely $TEXMFHOME/bibtool/.bibtoolrsc{,.rsc}. $TEXMFHOME is more specialized to (La)TeX, and, in my opinion, a better location than ~ for the default configuration for related tools such as BibTool.

Since $TEXMFHOME is searched by default by LaTeX and related tools, I think BibTool should also search it by default.

Well, on a UN*X system most configuration files for programs can be found under ~ and having a file or directory name starting with dot followed by the program name.
BibTool follows this convention. It feels more like a stand-alone tool than being part of a TeX distribution.
