[Proj] NTv2 grid between Belgian Datum 72 and ETRS89

[SIMON Nicolas]

Hi Proj community,

 I'm the author of a NTV2 grid to convert Belgian Datum 72 to ETRS89.
 This grid increases the accuracy of the convertion between Belgian Lambert 72 (EPSG 31370) and Belgian Lambert 2008 (EPSG 3812).
 It has been validated by Service Public de Wallonie (SPW) and Institut géographique National (IGN) as you can see on http://www.ngi.be/FR/FR2-1-7.shtm

 My request is, can you include a link in https://proj4.org/resource_files.html for Belgium with somethings like that
Belgium NTv2.0
      Belgium Datum 72 to ETRS89
      Source : Nicolas SIMON, with a link to http://www.ngi.be/FR/FR2-1-7.shtm
      Format : NTv2

I'll be glad if the grid can be included in the proj-datumgrid/europe/ package

I am open to any form of communication to make this information known.
Let me know.

Thank you

Best regards
Nicolas SIMON
