@RexWzh can you also work the rename stuff (QRCode => QRCodes or QRCoders) of this package before making a release? https://github.com/JuliaImages/QRCode.jl/pull/9#issuecomment-1113939138

[RexWzh]

Get. Changes are as following:

1. filename: src/QRCode.jl => src/QRCoders.jl
2. sourcecode, docs: QRCode => QRCoders
3. Project.toml: QRCode => QRCoders

Questions about package development:

• the uuid, version in Porject.toml remains unchanged (version + 0.1?)
• do the reponame and registration info need to be modified accordingly?

[johnnychen94]

Okay, I've renamed this repo to QRCoders and created an archived fork version https://github.com/JuliaImages/QRCode.jl for legacy usage. Now we can simply treat it as a new package and reset the version to 0.1.0. We'll need a new UUID as well.

We can merge this PR and do the rename work in another PR.
