Ifort changes compiler version format

[hiker]

The old ifort compiler changes the format version from 2 digits for year to 4 digits:

That makes for strange looking tests, e.g.:

    if (19, 0, 0) <= ifort.get_version() < (20, 0, 0):
...
    if (19, 0, 0) <= ifort.get_version() < (2022, 0, 0):

Should we care? We could adjust the version numbers in Fab to be consistent, but:

1. should we bother (ifort is unsupported)
2. do we create more confusion than we solve?

I am happy to just close this and accept the odd looking tests in Fab build scripts.
