`id` is missing from `Log` typing in documentation

[kgrhartlage]

The current documentation reads:

type Logs = Log[]

interface Log {
  // The log method
  method: Methods
  // The arguments passed to console API
  data: any[]
}

However, id seems to be supported and is used for the list key prop. This helped me resolve a bug in my application where we start to mutate the logs array once a max length is reached, while new logs are still coming in.

If desired, I can open a PR to update the README.
