Tweak size

[jeetiss]

I applied some optimizations to reduce bundle size:

• sideEffects: false to improve dead code elimination
• removed default export in _u64
• migrated _assert and _u64 module to wildcard imports to enable tree-shaking
• added /*#__PURE__*/ annotation to all top-level invocations

i used #62 to test changes

[paulmillr]

run big-endian check in every entry and mark it as sideEffect

why? does sideEffects: false in package.json help us in any way? i've thought only PURE annotations do.

[jeetiss]

• sideEffects: false allows to webpack skip unused imports earlier and not traverse over all module tree
• sideEffects: false decrease the bundle size for all entries ~100B-300B
• it also breaks the big-endian check because webpack will remove it
• I moved the check to a separate file and marked it as a side effect so webpack would enable that greedy tree-shaking and would keep the big-endian check always in bundle

made a little demo with stackblitz to test that behavior

@paulmillr Hello, Are you interested in those changes? I wanna create some PR for the curves package.

[paulmillr]

@jeetiss thanks for the pull request. It's good. Yes, I am interested.

I am concerned with moving-out big-endian check into the separate file.

It's always used. Can't we just keep it in utils? I assume sideEffects: false remove it, but what else do they remove?

[paulmillr]

Please don't make curves PR until we merge the current one, don't want you to do work that won't be merged.

[jeetiss]

I think it should be better to split this PR into a couple:

• one with pure notations
• second with migration from default exports to wildcard imports
• and third with sideEffects: false

The first two are not so controversial and we can discuss options for sideEffects after
