Implement the new ro.onrc identifier

[dotbit1]

Closes #464;
Tested with multiple new format codes.

Used https://targetare.ro/blog/schimbari-importante-la-registrul-comertului-ce-trebuie-sa-stii-despre-noul-format-al-numarului-de-ordine as a source of info.

The part about using the J, F, C ASCII values is wrong, it should be the number of the letter, etc J = 10, etc.

Hi @dotbit1,

Could you include the numbers you tested with?

Hi Arthur,
The code I wrote makes the existing tests fail.
The way I find 100% valid codes is: go to https://mfinante.gov.ro/ro/web/site/info-pj-selectie-nume-si-judet,
write some text that is likely to have many company names, ex. 4 letters and search,
then check each out and see if they have the new format.

Below a few examples:
J2012000750528
J2007007766403
J1992002621040
J1994000536225
J1993001036400

Hi @dotbit1,

Sorry for taking so long to pick this up.

From my understanding the new format will be used alongside the old format. The old numbers will remain valid and old numbers will be replaced by new ones gradually. This means that old numbers will need to remain to be accepted as valid for the foreseeable future (and the existing tests shouldn't fail).

Thanks for providing the source of more numbers. I've simplified the code a bit, extended the test suite and merged it as cd94bf1. I sadly didn't find any numbers in the new format for individuals (F numbers).
