Add a Hardware table to Wiki

[Mannshoch]

For using Phoniebox you need several hardware.

I propose to move hardware details from Readme.md to wiki.
Add a table per follow categories

• Board
• Scanner
• Speaker and suppressor
• Chips and cards
• Powerbank and addons like onoffshim
• buttons
• screens and other effects

A table should contain:

• hardware information (that help find the correct to buy)
• hardware details (frequency, voltage, technical details)
• link to ressources
• pros and cons of the device
• setup details

Create a new Discussion template to issue a new hardware for the Table.
