v0.6.0

New! ✨

• Class-based API + concurrent streams + column selections + File reader by @H-Plus-Time in #407. This added a new ParquetFile API for working with files at remote URLs without downloading them first.
• Conditional exports in package.json. This should make it easier to use across Node and browser.
• Improved documentation for how to use different entry points.

Breaking Changes:

• arrow2 and parquet2-based implementation has been removed.
• Layout of files has changed. Your import may need to change.
• Imports are now parquet-wasm, parquet-wasm/esm, parquet-wasm/bundler, and parquet-wasm/node.
