Remove defaults

[marchaos]

Hey. In https://github.com/thelicato/pino-rotating-file-stream/blob/main/src/index.ts you set some default values, but in my case I don't want to have an interval, but with those I cannot set it to undefined.

Are you able to remove those default values so that those can be undefined?

Hello, the interface PinoRotatingFileStreamOptions extends the Options interface defined in the rotating-file-stream package.
It should be defined here: https://github.com/iccicci/rotating-file-stream/blob/master/index.ts#L55

Since the values you are referring to are optional I think you can manually set them to undefined/none.
I haven't tested it out, so please let me know if it works.

I'm also running into this problem with compress: false which doesn't work due to the defaults. (Sorry compress is a bad example since false isn't supported by rotatingfile-stream`)

This doesn't work because the defaults are using || which means a falsy value of undefined or false will all fallback to the specified defaults

pino-rotating-file-stream/src/index.ts

Lines 13 to 16 in 53a9d14

	size: size || '100M',
	maxSize: maxSize || '1G',
	interval: interval || '7d',
	compress: compress || 'gzip',

For example

// assume interval = undefined

undefined || '7d'
// '7d'

Sorry actually looking at the rotating-file-stream library, it looks like they actually don't accept undefined for a lot of values, including interval

Error: Don't know how to handle 'options.interval' type: undefined

    at createStream (C:\Users\longz\Documents\GitHub\pino-rotating-file-stream\node_modules\rotating-file-stream\dist\cjs\index.js:579:18)

I'm not sure why they made the type optional

https://github.com/iccicci/rotating-file-stream/blob/e4a46274e672920fcb38b0cdf65ddc3e2ea7da6c/index.ts#L62

but then don't actually support undefined

https://github.com/iccicci/rotating-file-stream/blob/e4a46274e672920fcb38b0cdf65ddc3e2ea7da6c/index.ts#L601

With that in mind then, I guess this library always setting some defaults even for falsy values makes sense.
