* Unvendor toml package * Fix many ESlint errors For mysterious reasons, these errors appear on my branch #1262 even though they are not related to changes there. The eslint config seems a bit unstable. Anyways this fixes them. * Put back Record * Fix typescript compilation * Fix lints * Try @iarna/toml instead * Fix import * Use @ltd/j-toml * Update test * Use toml-j0.4 * Some changes * Fix toml import * Try adding eslint gha job * Add forgotten checkout action * Force CI to run * Blah * Fix * Revert changes to github workflow * Fix lints * wget toml-j0.4 type definitions * Add toml-j types workaround to eslint workflow * Apply formatter * Use @hoodmane/toml-j0.4 * Import from @hoodmane/toml-j0.4
