Version 2.0.0

Release summary:

Dropped support for Node.js 6, removed a bunch of deprecated and
outdated methods, replaced remaining ES5-style classes with ES6 classes,
and added changelog and utility methods for `Iterator`.

Changelog:

Added:

- CHANGELOG.md file.
- `Iterator#collectWith()` now returns the provided object.
- `Iterator#toObject()` to collect iterable into an Object similar to
  `Object.fromEntries()`.
- `common.iterEntries()`, `common.iterKeys()`, `common.iterValues()`
  utility methods.

Changed:

- Expose `AuthenticationStrength`'s `compliance` number property instead
  of `strength` string.
- Replaced ES5-style classes and iheritance with ES6 classes for `Cache`
  and `EnhancedEmitter`.
- Signature of `merger()` in `mergeObjects()` to also contain the
  merging key.

Removed:

- Dropped support for Node.js 6.
- Outdated `inherits()` method (in favor of `util.inherits()` available
  in Node.js).
- Multiple deprecated functions:
  - `common.ip2int()` - replace with `common.ipToInt()`
  - `common.cb()` - replace with `common.once()`
  - `common.extractCallback()` - replace with `common.unsafeCallback()`
  - `common.cbUnsafe()` - replace with `common.unsafeCallback()`
  - `common.cbExtract()` - replace with `common.safeCallback()`
  - `common.crcSID()` - replace with `common.crcToken()`
  - `common.generateSID()` - replace with `common.generateToken()`
  - `common.validateSID()` - replace with `common.validateToken()`
- Functions that can be replaced with `util.deprecate()` available in
  Node.js:
  - `common.deprecate()`
  - `common.alias()`

Fixed:

- Functions `common.clone()`, `common.deleteByPath()`, and
  `common.mergeObjects()` throwing when used on objects without
  prototype.
