Captcha almost impossible to solve

[weex]

Issue Summary

The captcha is almost impossible to solve due to noise, lack of contrast, case-sensitivity (which is unknown to the user) and audio playback only vocalizing the first character.

Steps to Reproduce

1. Go to https://lemmy.ml
2. Attempt to register a new account which requires solving the captcha.

Technical details

Using Chrome on Mac OSX.

Hrm, the audio playback only playing the first character is a bit strange, I tested and found it does do that on multiple replays. I recently let the captcha-rs library handle that, maybe I shouldn't have.

The default difficulty is currently medium, I spose we could change that to easy.

Created a PR for this. Let me know if you'd like any changes.

Closing since the case-insensitivity was merged. Audio can be raised in another issue.
