Update the CSV import to take in a some extra fields

[SimiHunjan]

Problem

Include the addition fields to read from the CSV:

• Transaction fee
• Transaction valid duration
  

Solution

if there is no transaction fee payer ID populated, use the sender account ID
If there is a transaction fee payer ID populated, use that as the transaction fee payer
If there is a transaction fee, use that as the max transaction fee value
If there is no transaction fee, use the default max transaction fee value
