Find a given tag in a compact TLV structure @param[in] buf input buffer holding the compact TLV structure @param[in] len length of the input buffer @buf in bytes @param[in] tag compact tag to search for - high nibble: plain tag, low nibble: length. If length is 0, only the plain tag is used for searching, in any other case, the length must also match. @param[out] outlen pointer where the size of the buffer returned is to be stored @return pointer to the tag value found within @buf, or NULL if not found/on error
