chore(#864): change instanbul to nyc for coverage on all projects

[mdebarros]

• Added .nycrc.yml with standard Mojaloop code-coverage milestones
• Updated test:coverage & test:coverage-check script in package.json - removed unnecessary configs defined in the .nycrc.yml
• Added Todo in README.md with note about future code-coverage improvements
• Minor bump to patch level to reflect dependency updates
• Fixed audit-resolve issues:
