Update cogent3 requirement from >=2026.4.13a0 to >=2026.5.19a0

[dependabot]

Updates the requirements on cogent3 to permit the latest version.

Changelog

Sourced from cogent3's changelog.

Changes in release "2026.5.19a0"

This is a feature enhancement release.

API

• added a SequenceParserBase.accepts_converter property. By default, this returns False. The cogent3 iterative parsers (fasta and genbank) are modified so its True. The top level sequence load_* functions use this to conditionally inject a converter into the parser_kw which directly converts plain text into the numpy.uint8 consistent with the moltypes most degenerate alphabet.
• added alphabet.bytes_to_array(dest=None) as an optional keyword argument. This takes the explicit destination bytes. The default behaviour (takes only non-redundant source alphabet characters and maps to ordered characters for conversion to numpy.uint8) is unchanged. This new argument allows redundancy in the input / destination character values. It's being used by the revised parser behaviour to streamline ingesting sequence data from files.

Enhancements

• the fasta and genbank iterating sequence format parsers use the new scinexus.io_util.iter_record_chunks streaming parser. This reduces peak RAM while retaining speed.
• improve generality of load_seq for json files, accepts all sequence classes
• alphabet.make_text_to_array_converter() function, returns a bytes_to_array instance that directly transforms sequence text file contents into a numpy.uint8 array. This avoids multiple bytes translation calls, improving speed and reducing peak RAM.

Changes in release "2026.5.14a0"

A bug fix and enhancement release.

Enhancements

• Performance of <seq coll>.get_lengths() on the sequence container classes now much more efficient.
