Get salary history

[yukiwaki]

[Overview]
When they borrow money, we should check their salary history based on the employer address and employee address (connected address).

We should get
・how long the stream runs
・How much they receive (total / monthly)

Use the FlowUpdated events and StreamPeriods

How much they receive (total / monthly)
This page in our docs has a formula + query you can use to get the total amount streamed from one account to another: https://docs.superfluid.finance/superfluid/developers/subgraph#getting-stream-data-between-2-parties

*we need to make wallet address lowercased with The Graph limitation

how long the stream runs
And for stream duration, you can get when the stream starts by filtering flowUpdated events for type of 0 (which represents a creation event), and 2 (which represents a deletion event)
