* Update dependencies, version and transition to ESM

* Use ESM imports, add ESM-related info

* Remove rollup

* Lint TypeScript-related files

* Update dependency

* Lint & update dependency

* Lint

* Remove commonjs tests

* chore: update changelog

* Remove commonjs GitHub action

* Update funding.yml

* Update linter rules

* Lint

* Fix tsd

* Remove unnecessary types

* Simplify

* Use top-level await

* Update GitHub Actions

* Use Mocha with ESM

* Revamp

* specify what node version

* update formdata-node dep

* remove lint from example using top await

* updated name and link to formdata-polyfill

* Stop recommend form-data

* filter example - it has many duplicate variables

* Update type definitions to ESM

* Remove unused lint rule disable comment

* Remove leftover rollup and dist folder

* updated depn

* updated d.ts

* lint

* Fix breaking changes with blob v3 stream()

* revert eslint comment

* revert back to xo 0.39

Don't want to deal with all those new rules right now. will fix it later
fixed some of them...

* none TS fan trying to fix type definition

* Give me a break

* Test on all minimum supported Node.js versions (#1170)

* Test on all minimum supported Node.js versions

* Tweak Node.js workaround version range

* Handle Node.js 16 aborted error message

* fix node version string compare

Co-authored-by: Jimmy Wärting <jimmy@warting.se>

* bumped fetch-blob version

* import from dom lib

* rm unused comment

* updated required version in docs

* fixed named import

* set lowest support to 12.20.0

* comment explaining both

* rm log
