Add initial implementation

[niksy]

As per sublimelsp/repository#120 (comment), this PR adds initial implementation for language server.

Waiting on:

• fix: update node to 20.18.0 lsp_utils#125

[rchl]

It does not work with v18?
We are currently including 18 with lsp_utils so it would be quite inconvenient if it wouldn't work with that.

(that said, it's probably a good time to update to 20 in lsp_utils)

[niksy]

I’m following what is defined in language server package.json engines field: https://github.com/wkillerud/some-sass/blob/main/packages/language-server/package.json#L14

I suppose it could work with Node 18, I know I’ve used it before I switched to Node 20.

Then it's time to update node version in lsp_utils I think.

[rchl]

Doing in sublimelsp/lsp_utils#125.

We should release those at the same time (or lsp_utils first).

[niksy]

I’ve update PR description to reflect this.

There is a custom command that the server triggers from code actions after selecting some text: https://github.com/wkillerud/some-sass/blob/0623e9162d70fd526f87b5185459801c9e481b67/vscode-extension/src/client.ts#L170-L234

This would need to be implemented manually in here.
But it's not a blocker for now I guess.

Oh, haven’t seen this one. Is there any previous work in other LSP plugins on how to implement those custom commands?
Should we create issue for this and revisit after initial publish?
