(devel/R-fansi) Updated 1.0.4 to 1.0.6

## v1.0.6
  * Fix new `-Wformat` warnings.

## v1.0.5
  * Address roxygen2 breaking changes:

  * Add explicit alias for `fansi-package` now that it is no longer
    auto-generated by roxgen2 from the [`@docType package`
    directive](https://github.com/r-lib/roxygen2/issues/1491).
  * Work around [changed behavior for
    `@inheritParams`](https://github.com/r-lib/roxygen2/issues/1515).
