Can't install because of `Sake` dep instead of `sake`

[Altai-man]

Apparently, in META6.json of Sake sake is used as a name. Then:

I am using 2019.11 and latest zef.

Yeah, I've seen that. I'm not sure if it's a bug elsewhere or if META6.json should be simply tweaked. Should it know that sake and Sake are the same thing? Ping @ugexe.

I filed a zef bug report -- https://github.com/ugexe/zef/issues/327 -- but this might be a bit tricky to fix. Looking at the grammar I expected escaping the < and > ala :auth<Foo \<a\@b.com\>> would avoid the issue, but apparently the grammar is not properly parsing escaped surrounding brackets.

This can be worked around by adding an auth field that doesn't contain < or > like :auth<First Last <foo@bar.com>>. Right now the author field is used as an auth since the auth field is missing, since that is just what was always done.
