Buyback Program for Voxelglyphs

Context

The recent turnaround in ETH markets and observed differences between market prices and NAV-driven valuation have made buybacks more attractive to the DAO.

Proposal

1. Make up to 100ETH from our vault available to execute Voxelglyph buybacks;
2. Allow buybacks to be made up to the NAV price considering the "Midpoints" valuation method of the Fingerprints collection, published by the NAV spreadsheet daily;
3. Allow buybacks to be made for up to 180 days from the date of approval of this proposal.
