docs: created DEVELOPMENT.md with some tips

[BigLep]

This includes some info I would have wanted when working on FilOzone/filecoin-services#380 (or it includes the headers I wish were there).

[BigLep]

@SgtPooki : I'm hoping you can help fill this out. It includes the things I wish I had seen documented when working on #299 as part of FilOzone/filecoin-services#380 today. No rush on this. Just didn't want to lose it before I move to other things.

leaving some comments, will come back to fix

you can also run npx filecoin-pin or npx . to run the local version when you're in the package root. Note the foobar123 in the second npx filecoin-pin run when i'm in the package root.

this works for non-built versions, or you can use bun, or you can run npm run build && npx filecoin-pin in the package root
