ProjNET only supports [] objects

[pchilds]

https://docs.geotools.org/stable/javadocs/org/opengis/referencing/doc-files/WKT.html states that "Implementations are free to substitute standard brackets ( ) for square brackets [ ] and should be prepared to read both forms of brackets" ProjNET should change its hard coded parsing of square bracketed items to permit the usage of parentheses.
