Update top-level Git mailmap to normalize commit author variants

[sbesson]

This PR updates the top-level mailmap to normalise all historical Bio-Formats contributors and have a single canonical real name and email address per contributor. The following rules are used for the construction of the .mailmap file:

• for all contributors who were also employees of the University of Dundee, Glencoe Software or the University of Wisconsin, the @dundee.ac.uk, @glencoesoftware.com or @wisc.edu email address is used as the canonical email address
• for all contributors with an executed CLA, the real name and email address sent via the CLA is used as the canonical address
• for all contributors, the name used in https://www.openmicroscopy.org/teams/ or https://www.openmicroscopy.org/contributors/ is used as the canonical real name.

The .mailmap is constructed according to the official documentation using one of the two forms:

Proper Name <proper@email.xx> <commit@email.xx>

for mapping different email addresses and

Proper Name <proper@email.xx> Commit Name <commit@email.xx>

for mapping different real names.

The unique list of commit authors can be generated and reviewing using git shortlog -se

Few typos as noted, otherwise looks like these are missing:

2  Aaron Avery <aaron@Aarons-MacBook-Pro.local>
1  JulyChen728 <602114946@qq.com>
3  LambertJohan <45658761+LambertJohan@users.noreply.github.com>
4  Parm0n <ilya.parm@gmail.com>

From https://www.openmicroscopy.org/contributors/ and public mailing list archives, I'd expect those to be:

• Aaron Avery <aaron.avery@healthmyne.com>
• https://github.com/JulyChen728
• Johan Herz <johan@lambertinstruments.com>
• Ilya Parmon
