Add benchmark dir in tests

[smol-ninja]

Same as sablier-labs/v2-core#908

[PaulRBerg]

it would be helpful to provide this, a user just asked about it

[smol-ninja]

Alright. Marked it as a higher priority

[smol-ninja]

Any suggestions on the benchmark table? I assumed that users might be more interested into understanding gas usage based on batch size rather than number of segments/tranches. The latter is already documented in the v2-core repo.

Do we also want benchmark tables for MerkleLockupFactory and MerkleLL/LT contracts? IMO that should not be necessary since Airstream campaign creators are usually the companies which have very few incentive to care about transaction cost.

[PaulRBerg]

Yes, batch size should be more important than the number of segments/ tranches. Feedback:

• A batch size of 2 isn't helpful. Users can just look at single streams and double the gas cost to estimate it. Let's do a size of 30 or 40 instead.
• Can we do 24 segments/ tranches instead of 5 (two years' worth of vesting)?

[smol-ninja]

• Instead of [2,5,10,20,50], we want [30,40,50]?
• Yes we can do 24 instead of 5 for segments/tranches.

[PaulRBerg]

Let's do [5,10,20,30,50].

[smol-ninja]

I now remember why I avoided large number of segments with higher batch size. Because it exceeds, block gas limit. With 24 segments, its not feasible to have batch size of more than 30 in LD and LT.

How about with batch size of 50, I change segments/tranches to 12 i.e. one year's worth of stream?

Sounds good!
