Allow many ':' in attributes

[RedPhoenixQ]

To do this, try_namespace_name now looks for nested namespaces. Because try_name'gets called, another Ident must be consumed to prevent and early return, which means that :: would not be valid, but a:b-c:d would be fine.

This allows for more custom attributes from different frameworks, specifically htmx's hx-on as mentioned in #194 (comment).

This is my first PR, I'll gladly take critique and make any changes necessary

Could you add support for alpine.js as well for '.':

x-on:scroll.window="showBar = (window.pageYOffset > 20) ? true : false"

I don't think this is easily done while keeping the class shorthand. Since the macro doesn't see whitespace foo.bar is the same as foo .bar which would be a valid attribute and then a class name via the shorthand.

The only way to do this would to somehow replace or escape the period . in the attribute name or add an escape character that would have to be a recognized Rust token. \ cannot be used as it isn't part of Rust syntax. Something like *. or ^. could work but isn't very elegant.

I don't want to make a change like class shorthand can only appear immediately after the element since that would be a breaking change.

Any idea how difficult it would be to add quoted attribute supported as mentioned here

[RedPhoenixQ]

Though about it and just tried it. I seem to have it working and will be making a new PR for that change, since it is not related to the changes in this PR.

#396 Now fixes the same issue by allowing "literals"="true"

Would like to see this feature too 👍 #396 would be just as good 👍
