[TOOL IMPROVEMENT] Improve usability of Token Generator length slider

[lukasgabriel]

The 'length' slider in the Token generator should a) allow numerical input as an alternative to moving the slider around, b) snap to common values such as 64, 128, 256, and c) display little guide lines above or below these commonly used values (see example picture.)

I love this awesome toolbox you have put together and am trying it out right now 😄

One thing I immediately noticed with the Token generator tool was how frustrating it was to hit the number you want, esp. for people with higher mouse sensitivity or movement impairments.

The slider could benefit from numerical input or snapping, in addition to some guide/hint lines to indicate the values it's snapping to.

Hi @lukasgabriel Thank you for those kind words 🙏🏻

I plan to rework every ui components (see #400 ) and I have the lake of accessibility of the slider in mind, so it's planned 💪🏻

it would also be nice to have the ability to exclude ambiguous characters , like don't add capital i and lower case L (Il) zero 0 and letter O
