Add a possibility to see sizes of whole bundles

[Beraliv]

Currently our approach is to reduce a size of separate methods, not a whole bundle

It should be possible to see the sizes of whole bundles nonetheless:

• To add a flag --bundle
• To create a bundle
• To check sizes of last nanoutils, ramda, (maybe lodash and underscore later) and etc.
• To write values to SIZES.md to compare them

Analysis:

• To create common internal methods to reduce a size of nanoutils' bundle

Check babel-nanoutils-plugin for partial builds:

• To check if common internals are loaded correctly
• To reduce a size of similar methods together
• To check if partial builds are working in production correct

@Kelin2025 obviously it can be checked like that
what about dev bundles?
