feat: add wakatime integration

[kcoderhtml]

I wanted to have some sweet wakatime stats on my GitHub profile but didn't want to deal with another tool, so I added it to this!

Lmk if you need anything changed or moved around :) (btw love charmbracelet stuff in general, y'all are great)

Closes #11

[kcoderhtml]

I fully tested the new integration and all additions to the README have been verified to work :)

The new bar format can be run on any of these:

{{ wakatimeData.Languages | wakatimeCategoryBar 5 }}

📜 Categories:

📦 Dependencies:

[kcoderhtml]

"Dependencies" is empty simply because I don't have any in my wakatime data
