Error when date/time has a Z suffix

[rpavlik]

Current reuse generates SPDX files with dates/times like this:

Created: 2024-04-29T18:23:30+00:00Z

Unfortunately, DateTime::parse_from_rfc3339 does not consume the trailing Z, so the parse fails. (This is being called from spdx-rs-0.5.5/src/parsers/mod.rs line 249, for example).

Running the following will postprocess a spdx file to make it parseable but this is a hacky workaround:

sed -i 's/00Z/00/' summary.spdx

It's unclear to me what the best approach here is.
