[BUG] sozo test high RAM usage (20GB+)

[rsodre]

Describe the bug Running any simple tet on pistols consumes 18-20GB of RAM

To Reproduce

• clone pistols
• cd dojo
• sozo test -f test_initialize_table (any test will demonstrate there problem, this is a very simple one)
• open Activity Monitor on macOS or a similar status monitor
• go to the Memory tab and filter by sozo
• while sozo builds, used memory goes up to 9GB, when it starts to run tests, it doubles and stays ~17-20GB

and please notice this gas consumption on simple tests (test_initialize_table_defaults)...

$ sozo test -f test_initialize_table
testing test(pistols_unittest) pistols v0.10.0-3 (/Users/roger/Dev/Realms/pistols/dojo/Scarb.toml)
running 2 tests
test pistols::tests::test_admin::tests::test_initialize_table ... ok (gas usage est.: 52,242,666)
test pistols::tests::test_admin::tests::test_initialize_table_defaults ... ok (gas usage est.: 54,464,862)
test result: ok. 2 passed; 0 failed; 0 ignored; 233 filtered out;

Additional context

• using Dojo 1.0.0-alpha.6 + Scarb 2.7
• The project uses the origami_token package ERC-20 and ERC-721, and some openzeppelin utils.
• Note that I have to include openzeppelin_test_common to be able to run tests, even if not using any openzeppelin in the tests

just to add some quick context, i checked the memory usage on spawn-and-move example that is in the repo and memory usage was around 1.2GB for build and 3.5GB for running the test (it only has couple of tests).

and since sozo build and sozo test are light wrapper around scarb i dont think the issue is specially related to sozo, i will do a memory profile to confirm this.

origami token package: ~4GB during build, ~8.5GB during tests

sozo test --package origami_token

@rsodre please can I be assigned

[glihm]

For the record, scarb has also notice significative increment of the compilation time. We may depend on what their bottleneck is.

@ShantelPeters do you have an idea of what could be dojo bottleneck related to compilation? Happy to assign if you have some suggestions.

[rsodre]

Is there an scarb issue for that?

The language server is also consumes around 6GB.

Btw, running the same test with Dojo alpha 9, it's around 13GB
