Template to standardize enclosure designs

[kdmukai]

We should formalize and structure the READMEs for the various enclosure designs, similar to how bitcoin BIPs are rigorously templatized.

Many of the existing enclosures do have some similar structure that we can leverage but we have not rigorously applied this.

Expected fields like:

• Design name
• Photo
• Designer ("@" reference to their github profile)
• Perhaps allow for an external link to a social media post from the creator (e.g. "Unveiling my new design..." tweet thread)

And then more descriptive sections like:

• Characteristics (which itself is a kind of formal list in some of our existing READMEs)
• Rationale / Design Goal(?)
• Credit to previous designs(?)
• Secondary Hardware Required
• Assembly Demonstration (link to video) or Assembly Steps (written instructions)
