Install issues

[JensRantil]

I'm following the README and I get this:

$ go get -v -u github.com/dimagog/direct2ledger
go: downloading github.com/dimagog/direct2ledger v0.0.0-20211019044934-4f0a9e10fba5
go get: github.com/dimagog/direct2ledger@v0.0.0-20211019044934-4f0a9e10fba5: parsing go.mod:
	module declares its path as: github.com/Dimagog/direct2ledger
	        but was required as: github.com/dimagog/direct2ledger

I'm using MacOSX with case-insensitive file system if that's relevant.

I don't have Mac OS, and cannot repro on Ubuntu.
If you have a fix, PR is welcome.
