Support extended camelCase options

[TonyGravagno]

According to the Google TypeScript Style Guide, Type identifiers should be in UpperCamelCase. Unless someone points out a difference, I'll settle for PascalCase.

PascalCase is implemented as an option on the camelCase(name) function:
camelCase(name, {pascalCase: true});

Since other options are possible, I'll implement this with a new camelCaseOptions option, which can be an object or null. The value of this option will be passed in to the camelCase(name,options) call without evaluation. I'll try to ensure that the Options match type Options from camelcase>index.d.ts>Options.
