Add support for custom initialisms

[zx8]

In my codebase, I use initialisms that are domain-specific and not included in Go's common initialisms.

The underlying strcase package supports customization, so I think it should be fairly simple to implement in tagliatelle: https://github.com/ettle/strcase#customization

If implemented, it would be great to also raise a PR to support the new configuration in golangci-lint.

Example of the problem:

json(goCamel): got 'docURLs' want 'docUrLs'

Closing as this is 2.5 years old without any movement.

To explain why this issue has not been fixed: even with custom options, the initialisms are not preserved.
So it's not possible to handle your example.

There is a PR on strcase (ettle/strcase#13) about this topic but it doesn't fix the problem with all cases (ex: VirtualIPv4 in kebab or snake case result in virtual-i-pv4 or virtual_i_pv4).

But I added an option (ignored-fields) to ignore fields https://github.com/ldez/tagliatelle?tab=readme-ov-file#as-a-golangci-lint-linter
