* Remove native screen reader support
Use the "accesskit" feature flag to `eframe` instead.
[AccessKit](https://github.com/AccessKit/accesskit) is the future.
`tts` was a mess to compile on many platforms, so I no longer want
the native `tts` dependency.
* Update tts to 0.25
* Update changelogs
* Turn on all feature flags for package.metadata.docs.rs
* remove tts from deny.toml skip-tree
* Update web build scripts
* Update deny.toml
* Fix docs.rs build issues for eframe, egui-winit, egui_glium, egui_glow
I hope we can get rid of the `tts` crate very soon,
now that AcessKit has landed. It is only used for web atm.
Should probably be removed from all native libraries.
* Update changelogs
