Support fields for week, month and color

[PanderMusubi]

Please, support fields for week, month and color. See the example at https://getbootstrap.com/docs/5.1/content/reboot/?optionsRadios=option1#forms

    <p>
      <label for="week">Example week</label>
      <input type="week" id="week">
    </p>
    <p>
      <label for="month">Example month</label>
      <input type="month" id="month">
    </p>
    <p>
      <label for="color">Example color</label>
      <input type="color" id="color">
    </p>

Hi. Thank you for your contribution. The MonthField already exists, even if it was not documented, though it is fixed now.

For the record:

• The MDN page on week input
• The MDN page on color input

Is a PR welcomed for week and color?

[PanderMusubi]

Thanks for merging the related PR and other PRs. Since the last release is one year ago, could you please make a new release so PyPI will include these these contributions?

@PanderMusubi are you interested in reviewing #765?

[PanderMusubi]

Looks good. Perhaps refactor

import datetime

to

 from datetime.datetime import strptime

@greyli can you have look too?
