ASDCPLib assumes that the Partition Pack length is a 4-byte BER Length

[palemieux]

A 4-byte BER Length is hard-coded in the size of a Partition Pack. I have not been able to find that constraint in ST 377-1.

asdcplib/src/h__02_Reader.cpp

Line 189 in 32220b3

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

Recommend:

• clearly indicating this ASDCP limitation in the README and/or inline the code
• consider removing this limitation
• consider amending the appropriate IMF and DCP standards to note that Partition Pack Lengths different than 4 bytes might cause compatibility issues
