Remove require(esm) support from package.json

jridgewell · jridgewell · commit e95784217661 · 2025-06-30T00:48:38.000-04:00
Looks like there's a bug with some versions of Node v22 that causes requiring one of the modules to throw a cyclic import error. Which is strange, because `sourcemap-codec` doesn't import anything. Fixes #30
