Add light sync command - Only syncs block headers (excludes block bodies, transactions, receipts, and logs) - Modifies validation window to include the most recent block - Isolates validation window to the variable defined in the cmd directory (blocks have a separate variable defined in the block_repository for determining when to set a block as final)
