Bump asdcplib to dcpomatic-2.13.0 branch.

Don't write MCA subdescriptors for channels that don't exist in the MXF (#2631).

2023-10-17T10:44:04Z

This causes some test ID churn.

Write OriginalFileName tags in PKL (DoM #2394).

2022-12-22T22:43:03Z

Without these it EasyDCP gives errors like "Id field in PKL must match uuid in asset" "Each Id used in the PKL files must be unique or reference the same file" which seem wrong but, as usual, here we are.

Set plaintext offset to 0 when writing J2K frames (DoM #2391)

2022-12-22T22:16:45Z

Without this the EasyDCP verifier gives errors like "sum of individual components is larger than the file size" This change results in there being no plaintext metadata in each encoded frame. It looks like the DCP-2000 was fixed in around 2010 to not crash with plaintext metadata, and the asdcplib tools at some point started defaulting to this behaviour also.

Make some tests repeatable across platforms.

Use optional for ReelAsset _annotation_text.

2022-01-17T19:16:52Z

Not only is this tag optional in Interop and SMPTE, but it would appear that if it is present but empty a DCP will not play back on Sony SRX320 / LMT3000 systems (DoM bug #2124). Here we use optional<>, as seems to make sense, and also refuse to write empty tags (instead omitting the tag entirely).

Fix tests after previous commit.

Test churn from adding make_uuid() into CPL.

Write MCA tags based on the specified sound field.

2021-03-25T23:09:15Z

I had previously assumed that one should write MCA information into the sound MXF based on what channels actually contain sound rather than silence. However a previous example of a stereo DCP gives a verification error in EasyDCP (see DoM bug #1935) which is solved by adding MCA tags for each channel in the specified sound field (e.g. at least 6 tags for a file which is marked as 5.1) even if the audio is really stereo. This commit removes the "active channels" stuff and makes sure that if we say a file is 5.1 we write at least 6 MCA tags (and similarly for 7.1).

Remove 32x32 test image.
