5.0.0

Changed

• Updated interface of BundleOrchestrator._transform reflecting tighter constraints in @types/node v14. No modification to runtime logic, method only used by NodeJS streams.
• Removed esm loader in favour of native ESM support.
• Raised minimum NodeJS version from 10 to 12.17.0.
• Changed exception type thrown when a configuration merge fails, consequence of changing error wrapper from errlop to @jsdevtools/ono.
