Path config with `~` on macOS seems to not work

Lately, I have switched from AsyncStorage to MMKV in on of the macOS test projects, and I would like to utilize the path config, but it looks like that, when path includes tilde (~) file is not saved. Not sure if this is intended to work, but I have decided to report this anyway, so feel free to close this one or convert to feature request.

Other thing which was a bit unexpected is that you cannot use the constructor with config object, but without the id field (no fallback to default?), so for example when path and encryption field are the only present, this leads to error about missing ID.

Repro

• Clone: https://github.com/Simek/react-native-macos-reminders
• Edit: https://github.com/Simek/react-native-macos-reminders/blob/master/src/Storage.js
• Add: path: '~/.test' config option

Start with the reproduction's src/Storage.js and confirm the behavior using the path '~/.test' on macOS. Then trace the path configuration and constructor validation in the relevant MMKV entry points. Done means the reported path behavior and the config without an id have clearly defined, tested behavior.
