Create a DER input stream from part of a data buffer with
additional arg to control whether DER checks are enforced.
The buffer is not copied, it is shared. Accordingly, the
buffer should be treated as read-only.
@param data the buffer from which to create the string (CONSUMED)
@param offset the first index of <em>data</em> which will
be read as DER input in the new stream
@param len how long a chunk of the buffer to use,
starting at "offset"
@param allowBER whether to allow constructed indefinite-length
encoding as well as tolerate leading 0s
