Expand LEGO committee by adding Tim Beiko

Tim Beiko (http://www.twitter.com/timbeiko, https://github.com/timbeiko), Ethereum's All Core Devs' cat herder, and a masterful explainer of all things Ethereum, is willing to join LEGO as a council member.

If this proposal passes:

• Tim will be added to LEGO council and, consequently, LEGO Gnosis Safe multisig as 7th member, with multisig's becoming 4-of-7 one;
• Tim will be allocated an individual budget of 15000 LDO out of LEGO's communal budget.

If it's rejected:

• No changes to the status quo.
