Add a how-to about Turris MOX (dis)assembly
Suggested notes to mention:
- link to an instruction video
- to be careful while pulling off the sides if a Wi-Fi card is included (antennas are glued to them)
- how to arrange the pigtails (especially the SDIO card; @jhoracek knows)
- the order or different modules matters + link to our configurator
