Equi7 support

[m-mohr]

EODC uses Equi7, but we can't properly encode and handle it right now.
Thus EODC will add a new field equi7:proj to the assets, which value is the proj string from the list below:

AF: '+proj=aeqd +lat_0=8.5 +lon_0=21.5 +x_0=5621452.01998 +y_0=5990638.42298 +datum=WGS84 +units=m +no_defs'
AN: '+proj=aeqd +lat_0=-90 +lon_0=0 +x_0=3714266.97719 +y_0=3402016.50625 +datum=WGS84 +units=m +no_defs'
AS: '+proj=aeqd +lat_0=47 +lon_0=94 +x_0=4340913.84808 +y_0=4812712.92347 +datum=WGS84 +units=m +no_defs'

@SerRichard Do you have an example for me?

[SerRichard]

Sure!

In the Canonical link, equi:proj is found per asset as discussed 😄

It doesn't work as expected yet even after loading the Equi7 proj string, so checking with OL whether there's an issue:
