Fixed SuiteSparse 6.0 version parsing

Browse Source 
The version component macro names are delimited by multiple spaces in
the new release resulting in a failure to parse the version.

An additional guard ensures that if the version cannot be correctly
parsed it is discarded and a user warning is issued.

Fixes #919
