0.2.3

Updated most dependencies to their latest stable versions, many of which previously suffered from security vulnerabilites. Most notably, this release:

• Replaced fuse dependency (which has not been updated in the past 5 years) with fuser, an actively maintained fork.
• Replaced frozen google-drive3-fork (based on google-drive3 version 1.0.10) with google-drive3 version 5.0.2. This brings in additional updates to re-exported packages (hyper, hyper_rustls, oauth2).
• Switched to an async/await model as imposed by the google-drive3 upgrade. Currently the project doesn't make any good use of this and enforces synchronous execution by wrapping any Future within a block_on(). Maybe this can be optimized in a future version.
• Slight changes to sample config, mainly regarding the client secret for Google API access.
