* AEP import: read image sequences without a filename prefix and with Force alphabetical order (#3174) After Effects leaves out an empty filename prefix, so only one Utf8 (the suffix, such as `.png`) follows the alias. The single part is now placed by the first file name stored in `opti`: a name starting with it has it as the prefix, one ending with it as the suffix; without that evidence a part starting with `.` is the suffix and anything else is not read. A sequence imported with Force alphabetical order stores its files in `LIST StVc` (`StVS` with the count as a little-endian u32, then one Utf8 per file name) instead of prefix and suffix; that list now replaces the numbering. A list with a name that is not a plain file name (a separator, a colon, `.` or `..`) is not read, since the names are joined to the folder. A folder alias whose naming still cannot be read is reported as an import loss instead of silently linking the folder. docs/aep-format.md describes the empty prefix and StVc/StVS. * AEP import: a listed sequence file name with a control character such as NUL is not read (#3174) A NUL or another control character in a Force alphabetical order file name now makes the whole list unreadable, like a separator or a dot directory, so the import reports the naming instead of linking files that cannot exist. * AEP import: a sequence file list without a readable count is not read (#3174) After Effects writes the StVS count before the names. A StVc list without StVS, or with one shorter than its u32, is now reported as unreadable naming instead of taking every listed name. * Doc comments for the functions this PR touches
