This improves the error checking in the
WKBReaderto detect field values which are out of range. The fields checked arenumElems,numRingsandnumCoords. They are checked to ensure they are > 0 and less than MAX_INT, and that they are less than the maximum size of the WKB data (if known). This should preventNegativeArraySizeExceptionandOutOfMemoryErrorerrors being caused by malformed or malicious WKB values.Fixes #67.
