Remove dependency to tsdx

[lourot]

(Similar to Frameright/react-image-display-control#23)

We scaffolded this project using https://github.com/jaredpalmer/tsdx, which isn't maintained anymore, leading to issues and workarounds like the overrides in https://github.com/Frameright/image-display-control-metadata-parser/blob/main/package.json

In our package.json scripts calling tsdx, most of the time it is only a wrapper around other well-known open-source tools, so we should be able to get rid of it.
