FR: Easier installation (and, eventually, updates)

[quicklywilliam]

Currently it is necessary to install KOReader before installing eReader. This requires several steps and a decent amount of technical knowledge . This fails to achieve the goal of making eReader as accessible as possible.

Some possible ways to achieve this:

• Write a single script similar to Kobo One Click Install.

Note that I've spent a ton of time trying to get a working build but keep running into corruption issues related to the install build zip file. Eventually we will probably need to get this working (cherry-picking over files in the deploy script is error-prone), but as an interim we could probably have a single script that does the current method of installing KOReader and eReader sequentially.

• A a simple native app or UI wrapper for the above script

This would be a fair amount of work to support each platform, get it signed on macOS, etc

• Install directly in a Webbrower via File System Access API

Probably a bad idea but it would be the most accessible…

• Build an Electron app or some other cross-platform app? Install via Homebrew? Other options?

Another thought: a one-step install (as opposed to the current sequential method) would require a lot of new infrastructure: CI, automatic release builds, a process for brining in upstream updates in KOReader, etc. At this stage, I don't think any of that makes sense and it begs the question of the long term relationship between eReader and KOReader (there are still a number of ways I could see eReader evolving, including potentially folding part or all of it back into KOReader).

Until we've resolved the above considerations, I'm going to have this issue also track having an update mechanism.
