Updates uuid, unicode-xid and base64 to reduce duplicate crate versions in projects.

Can you set the base branch for this to master instead of async?

@SergioBenitez the UI tests are a pain since (I think) rust-lang/rust#64151 - see e.g. https://dev.azure.com/SergioBenitez/Rocket/_build/results?buildId=246&view=logs&jobId=fe4e408a-5576-5fa1-f2ab-61ac24819df6&taskId=7f0864f1-1a96-5cff-86e3-45ee63058371&lineStart=1343&lineEnd=1361&colStart=1&colEnd=1

This has two problems. First, there is trailing whitespace after one of the |, so test.sh will complain after blessing the UI test. Second, that path isn't normalized/normalizable (at least not with $DIR). I had "fixed" this in the async branch by commenting out the complian-about-trailing-whitespace but the non-normalized path slipped my attention and it doesn't work.

I believe of these deps uuid is the only public one. This will be inconvenient for anyone using rocket and diesel in the same application, at least until diesel-rs/diesel#2205 makes it into a release.

Unfortunately uuid made a breaking change by changing uuid::parser::ParseError to uuid::Error so it wasn't possible to support both versions.

Can you rebase this on master to trigger a CI run?

[paolobarbolini]

It looks like the macOS build is failing because it's not finding mysqlclient

Thank you! Merged in cd5f96a.
