fix: add missing pilcom dependency

[mooori]

Code to run tests depends on pilcom:

wasmtime/tests/zkasm/run-tests-zkasm.js

Line 11 in ca0d6dc

} = require('pilcom');

Though pilcom is not a dependency. This hasn’t surfaced since zkevm-proverjs depends on pilcom, so it is available anyway. The missing pilcom dependency poses a problem when using a local zkevm-proverjs for debugging (e.g. helper usage).

// package.json: use local `zkevm-proverjs`
"@0xpolygonhermez/zkevm-proverjs": "file:<path>",

LGTM!
