bench: support large transactions

[grooviegermanikus]

Problem:
The rust bench tool used small transactions of only 179 bytes which is unrealistic.

Proposed Solution:
Add option to allow for large transactions:
cargo run --bin bench -- --tx-count=10 |--large-transactions (short -L)

transaction characteristics:

• uses memo program
• 1186 bytes
• 8 account signatures
• 240 utf-chars in memo progra
• 193175 compute units

Added transaction size to metrics:

No need to specify type. May be your ide issue.

[grooviegermanikus]

nah. sometimes is add them if the deduced type is too far away from declaration.
