.solcover.js configuration file is not taken into account when running coverage

[elenadimitrova]

solidity-coverage uses a .solcover.js configuration file to pass in quite a lot of really useful and necessary options into coverage. Some can perhaps be replaced with the etherlime coverage command options but most are just not there. Examples are the ganache-cli options via providerOptions, onCompileComplete option for provisioning external artefacts before tests are run (which also will likely solve #304 )

Thank you. I am going to fix it.
