🍏 Re-initialize Expired Subscriptions

[alecchendev]

When subscriptions expire, the rent from the deposit vault and metadata accounts are withdrawn, so if someone wants to use that subscription again, they need to reinitialize it. To differentiate subscriptions of the same type (i.e. payee, amount, duration) we store a count in a separate account and increment it every time we create a new subscription. If we reinitialize a subscription, we don't want to increment.

2 things to do

1. Have count be passed into the instruction as an argument
2. If count != latest count, don't increment

New development: just modify the program now to store count so you don't have to pass it in
