explorer: Not able to view "raw" account info for parsed accounts

[jstarry]

Problem

The explorer handles parsed accounts (tokens, stake, etc) differently from non-parsed accounts on the account details page. Rather than showing the SOL balance, account space, etc. it displays program specific information like token balance or activated stake. This means that some information is not readily available for parsed accounts or that Solana specific details are mixed with program specific details.

Proposed Solution

• Add a "Raw" toggle which behaves similarly to how the explorer displays parsed instructions
• Display the raw account data in HEX
