Update to work with parse5 7.0.0 and css-select 4.3.0

[MrLittleKitty]

Summary

This was not working with the latest versions of parse5 and css-select, so I updated it. Changes are below:

• Updated dependencies to recent versions
• Updated functions to work with new parse5 typing for TreeAdapter and other type constraints

Testing

Ran the included tests with tape:

C:\Coding\css-select-parse5-adapter\lib\test>node css-select-parse5-adapter.test.js
TAP version 13
# Lets try some selectors
ok 1 simple tag selector
ok 2 attribute selector *=
ok 3 class selector
ok 4 simple descendant combinator selectors
ok 5 attribute selector for class contains ~=

1..5
# tests 5
# pass  5

# ok

I also used this in my own project and confirmed that it worked there.
