account-decoder: don't use strings to convert between Pubkey types

[polachok]

Problem

It doesn't make sense to allocate a string for this operation

Summary of Changes

Use arrays instead

[CriesofCarrots]

Thank you, this is better!
There are a couple other places we use this pattern. Would you mind updating those as well?

solana/transaction-status/src/parse_associated_token.rs

Line 11 in ff0e623

Pubkey::from_str(&spl_associated_token_account_v1_0::id().to_string()).unwrap()

solana/transaction-status/src/parse_instruction.rs

Lines 24 to 25 in ff0e623

	Pubkey::from_str(&spl_memo::v1::id().to_string()).unwrap();
	static ref MEMO_V3_PROGRAM_ID: Pubkey = Pubkey::from_str(&spl_memo::id().to_string()).unwrap();

[polachok]

Sure, done

Thank you!
