Watch a conan installation

Watch a conan installation from another process. This can be used to stream the status and progress back to the current R process.

conan_watch(
  get_status,
  get_log,
  show_progress = TRUE,
  show_log = TRUE,
  poll = 1,
  error = TRUE
)

`get_status`	A callback to get the status of the installation. The callback will be called with no arguments and must return `COMPLETE` on successful completion, `ERROR` on failure and any other value to continue.
`get_log`	A callback to read logs of the installation (something like `function() readLines(filename, warn = FALSE)` may be sufficient)
`show_progress`	Logical, indicating if we should show a progress bar. This requires the progress package.
`show_log`	Logical, indicating if the installation log should be printed
`poll`	Time, in seconds, used to throttle calls to the status function. The default is 1 second
`error`	Logical, indicating if we should throw an error if installation fails.
