Added a feature to customize length of the pattern

[garciadelcastillo]

Includes a checkbox for square pattern or not, plus a text box for a custom number of rows.
Works with the state in the URL.

Hi @garciadelcastillo! Thanks for doing this. I'm about 80 minutes into the video. Cool stuff. Very sorry about the dependency troubles at the beginning. I think I made your life harder by merging a broken PR from dependabot.

Overall this looks great but I think it's a bit confusing that the Custom number of rows: question shows up even when the user has Square pattern? checked. What would you think of hiding that line until "square" is unchecked? (Or I can probably merge this and then take care of that myself if you prefer.)

[garciadelcastillo]

You are very right, that would feel better from an UI perspective.

Give me a few days and I will push some edits to this PR.

Great!

Thinking a little more, another option might be:

• rows input greyed-out if "square" is checked
• rows input (when greyed out) shows a number that exactly matches the height (since you have a square)

But what I said before would be good too I think.
