ESM support

[vladinator1000]

Hi there, I'm trying to use umap-js with Vitest, but I'm getting this error:

TypeError: Cannot use require() to import an ES Module.
 ❯ .../node_modules/.pnpm/umap-js@1.4.0/node_modules/umap-js/dist/umap.js?mf_vitest_no_cjs_esm_shim:8

Is ESM support planned for umap-js?
