Option to avoid history tracking in wnfs

[gotjoshua]

Summary

When writing many small files to a folder in wnfs, each new file creates a new nested history entry in the previous folder. This is not needed in my use case (as the files are actually history tracking CRDT records in and of them selves).

Problem

This creates an unnecessarily deep and complex nested DAG situation.
It even rendered my gotjoshua account completely useless.

Impact

I must say I find these template headers annoyingly overlapping and I do not enjoy attempting to comply.

Solution

my ideas:

1. inhibit history via a config option passed to wnfs add and/or publish

await fs.[add | publish](
  wn.path.file("public", "path", "to", "a", "file"),
  content,
  { history: false }
)

2. add a .historyignore file to any folder to permanently avoid history tracking for that specific folder
   • needs consideration about recursion

Describe alternatives you've considered
I tried deleting stuff, but of course its still in the history (and i guess the delete action also deepens the DAG)

Will be implemented when Webnative ships with rs-wnfs as the primary file system implementation. There's already a hint of this in the codebase, see "history stepping": https://github.com/fission-codes/webnative/blob/e323e8ea5ffa7861f546773db15c6ea29e305395/src/fs/filesystem.ts#L541
