targets 1.11.4

• Tone down progress bar output for medium-overhead scenarios.
• Speed up tar_meta() default settings for tar_read() etc. (for million-target pipelines).
• Choose the "terse" reporter by default if the calling session is non-interactive. This will hopefully avoid problems on CRAN for packages that use targets with the default settings.
• Improve reporter deprecation messages (#1493, @dakvid).
• Clarify scope of tar_renv() (#1506, @valentingar).
• Handle errors in rstudioapi::isAvailable() (#1519, @dipterix).
• Improve error message when metadata file is corrupted (#1523, @dakvid).
