Update dev dependencies (#220)

* update .gitignore

* update .travis.yml config

* update dev dependencies

* adjust code for rules in new semistandard version

* standardx with tweaks instead semistandard

* style changes for latest standard

* move bignum in benchmark to optionalDependencies

* add lock file for benchmark
