This package can't be used in a node environment using ESM as it's neither declared as "type": "module" nor does it include .mjs extensions for the files in the module main field.
Since TSC is not able to produce proper ESM files with .mjs extensions I opted to use tsup to compile the ESM files, and I also had to add @swc/core to keep this backwards compatible with the es5 target. I don't think there's much point in supporting back to es5 for an ESM, but I'm keeping it for now to avoid making this a breaking change.
Fixes #2353
