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
