Index table construction does handle KLV Fill Items after the Partition Pack

[palemieux]

Section 6.4 at SMPTE ST 377-1 specifies that a KLV Fill Item may be present immediately after the Partition Pack, before any Index Table Segment or Header Metadata.

ASDCPLib assumes that the Header Metadata and/or Index Table Segment come immediately after the end of the Partition Pack:

asdcplib/src/h__02_Reader.cpp

Line 183 in d417531

current_ec_offset = tmp_partition->HeaderByteCount + tmp_partition->ArchiveSize();

There is a branch flexible_header_parse that attempts to address this issue. It is ready for inspection if anyone has an interest.
