solana-tokens panics on bad recipient

[CriesofCarrots]

Problem

solana-tokens assumes that all recipient strings in the input-csv are parsable as Pubkeys, and panics if not.

solana/tokens/src/commands.rs

Line 183 in 105a6bf

let to = allocation.recipient.parse().unwrap();

solana/tokens/src/commands.rs

Line 278 in 105a6bf

let wallet_address = allocation.recipient.parse().unwrap();

Proposed Solution

Return an error when parsing fails. While it is correct for the distribution to be halted before any transfers occur, the panic does not identify the problem address. Consider building all the instructions and then returning errors identifying any/all addresses that fail to parse.
