same as rollup theres write and generate function

write is to persist or write file to disk

generate is to output string or objects like code, map

this is useful if someone will create a plugin or any tools using esbuild

i did jest transformer (https://github.com/aelbore/esbuild-jest),
im using rollup and rollup-plugin-esbuild then sync-rpc to wrap the async
it would be good if build api would output result string
