v8-argv warning

[ooflorent]

v8-argv@0.1.0 raises a deprecation notice.
Updating to 0.2.0 would solved it.

child_process: customFds option is deprecated, use stdio instead.

[Hypercubed]

First need to publish latest v8-argv (logicalparadox/v8-argv#4) then bump the dep (https://github.com/Hypercubed/matcha/tree/chore/npm-update).

(the v8-argv change is not in v0.2.0).
