Clear text without delay & update dependencies

[KilianB]

Main changes:

• add a clear method which removes characters in batch in a single event loop, thus no delay is noticeable. The current delete all version splits up deletion in single events which result in a delay because the loop is tick based.
• check the type of speed in deleteAll instead of if it is truthy. This will allow the user to specify a potential delay of 0
• Bump dependencies

Minor changes:

• typo fixes

React and react dom have been pinned to the current version instead of the .x release. This can and should probably be changed.

I also need this feature. Hopefully this PR will be merged soon.
