Add support scarb build generate json

[jujube]

A command similar to cairo-vm-cli
sarb build json:
for example: 1.hello_world.sierra.json the content inside {"version":1,"type_declarations":[{"id":{"id":0,"debug_name":"u64"},"long_id":{
2.my_contract_hello.contract_class.json the content inside {"sierra_program":["0x1","0x4","0x0" ... ...

Hello! Could you expand a bit more on the functionality that you need?

[jujube]

scarb new cairo0408
cd cairo0408
tree
.
├── Scarb.toml
└── src
└── lib.cairo

scarb build
tree
├── Scarb.lock
├── Scarb.toml
├── src
│   └── lib.cairo
└── target
├── CACHEDIR.TAG
└── dev
└── cairo0408.sierra.json

above for example 1.
I need new_cmd
new_cmd cairo0408.sierra.json as cairo-vm-cli cairo_programs/abs_value_array_compiled.json

So I understand what you need instead is something to run a sierra file instead of a cairo file for cairo1-run?
There is a PR open that targets this issue #1544 would this solve your problem?

[jujube]

now cairo1-run can run single cairo file.
we now use scarb.
scarb is Cairo's package manage.

There is no merge. so I am not sure if this can solve this problem.

This will be addressed in #1719
