Consider IPFS Helia for JSON transport/storage/replication

I think [helia/json](https://github.com/ipfs/helia#-json) would compliment TinyBase as a P2P remote storage solution using IPFS. It's a relatively new implementation of IPFS for browsers and my initial testing looks good. It stores plain JSON and uses ```add``` and ```get``` methods, so should be possible to use with TinyBase ```save``` and ```load```.

Thanks for a great project.
