Feature Request: Custom Format option using Javascript

[itsmariodias]

Hi there,

Love the card, but I realize that the format options are limited to specific options like kilo, relative, total, etc. If we need to format our values in a different value that's not possible (or not easy). Was wondering if you can provide a way for us to insert our own formatting options like say format: "x * 1000". I was initially thinking that it could provided as a javascript function, but I'm no expert on how these cards work.

The existing format: options have some conversion options. I suggest to break up transformation and formatting. So you could have transform: and the existing format:. For transform: you could borrow what Apex Charts does.
