[ADD] l10n/brazil: add antoniospneto as member

[rvalyi]

Hello OCA maintainers,

@renatonlima and myself would like to promote Antonio Neto @antoniospneto from the Brazilian Engenere company as a PSC for the OCA/l10n-brazil repo.

Antonio has been doing excellent contributions over the last 3 years: https://github.com/OCA/l10n-brazil/graphs/contributors

• over: 364+ quality commits
• 148+ merged PRs https://github.com/OCA/l10n-brazil/pulls?q=is%3Apr+is%3Amerged+author%3Aantoniospneto
• countless quality reviews
• authored a couple new modules
• contributed PRs on other OCA repos
• overall he helped a lot (fixed hard issues, found complex issues during reviews) with the l10n_br_fiscal module, the l10n_br_account module, the banking boleto/CNAB modules and many other modules.
• he has a good knowledge how open source works
• helped a lot during the v14, v15 and v16 migrations.

It is worth mentioning that OCA/l10n-brazil is simply the largest of all the OCA repos (both in term of code with over 130k lines of Python+XML and in term of commits with over 13k commits, making it weight as much as 10% of Odoo CE...) so we cannot accept anyone as a PSC even with hundred of commits as the responsibility is so huge in such a huge repo. But over the last 3 years @antoniospneto definitely reached the skills and contributions to be one more PSC of the project.

cc the 3 other PSC's: @renatonlima @marcelsavegnago @mileo and 2 other of the current top contributors: @mbcosta @felipemotter

also, I forgot to mention but @antoniospneto also helped a ton with the l10n_br_nfe Electronic Invoicing module, making the code a lot more cleaner and well tested.

Congratulations on the work done in recent years! It was about time! The Brazilian localization needs more contributors! May the open source spirit continue to be strong!!!!
