ms_sid2nsld() can be dangerous with malformed FDSN Source IDs

[chad-earthscope]

ms_sid2nslc() does not check the length of the parsed codes when writing to the output buffers.

Since the function does not know the size of these buffers, a caller may assume that a size of 9, to accept the longest possible code in the FDSN Source ID specification, would be sufficient. But if a malformed Source ID is provided as input with codes longer than allowed the function will continue to write beyond the buffer length. Chaos ensues.

Ideally this function would have arguments for the sizes of these buffers. Short of that, it should limit the output to the maximum code sizes allowed by the specification.
