Exception when selecting region with bad point string format (e.g. including float)

[kahlep]

TWI seems to sometimes write floats to the point string and when selecting that region in SwtGui an Exception is thrown (see bottom).

PointStrUtils can already handle this since Transkribus/TranskribusCore@32e3621

Transkribus/TranskribusCore@4d2975c adds this fix to PointStrUtils::buildPointContainer but still needs more testing.
