(sysutils/R-ps) Updated 1.7.7 to 1.8.1

# ps 1.8.1

* ps can now be installed again on unsupported platforms.

# ps 1.8.0

* New `ps_apps()` function to list all running applications on macOS.

* New function `ps_disk_io_counters()` to query disk I/O counters
  (#145, @michaelwalshe).

* New `ps_fs_info()` to query information about the file system of one
  or more files or directories.

* New `ps_wait()` to start an interruptible wait on multiple processes,
  with a timeout (#166).

* `ps_handle()` now allows a numeric (double) scalar as the pid, as long
  as its value is integer.

* `ps_send_signal()`, `ps_suspend()`, `ps_resume()`, `ps_terminate()`,
  `ps_kill()`, and `ps_interrupt()` can now operate on multiple processes,
  if passed a list of process handles.

* `ps_kill()` and `ps_kill_tree()` have a new `grace` argument.
  On Unix, if this argument is not zero, then `ps_kill()` first sends a
  `TERM` signal, and waits for the processes to quit gracefully, via
  `ps_wait()`. The processes that are still alive after the grace period
  are then killed with `SIGKILL`.

* `ps_status()` (and thus `ps()`) is now better at getting the correct
  status of processes on macOS. This usually requires calling the external
  `ps` tool. See `?ps_status()` on how to opt out from the new
  behavior (#31).

Log message:
(sysutils/R-ps) Updated 1.7.7

# ps 1.7.7

* `ps_cpu_times()` values are now correct on newer arm64 macOS.

# ps 1.7.6

* `ps_name()` now does not fail in the rare case when `ps_cmdline()` returns an \ 
empty vector (#150).

* `ps_system_cpu_times()` now returns CPU times divided by the HZ as reported by \ 
CLK_TCK, in-line with other OS's and the per-process version. (#144, \ 
@michaelwalshe).

Log message:
(sysutils/R-ps) Updated 1.6.0 to 1.7.5

# ps 1.7.5

# ps 1.7.4

* `ps::ps_get_cpu_affinity()` now works for other processes on Linux, not only
  the calling process.

# ps 1.7.3

* The output of `ps_disk_usage()`, `ps_disk_partitions()` and
  `ps_shared_lib_users()` now do not include a spurious `stringsAsFactors`
  column.

# ps 1.7.2

* `ps_system_memory()$percent` now returns a number scaled between 0 and 100
  on Windows, rather than between 0 and 1 (#131, @francisbarton).

# ps 1.7.1

* ps now returns data frames instead of tibbles. While data frames and
  tibbles are very similar, they are not completely compatible. To convert
  the output of ps to tibbles call the `tibble::as_tibble()` function
  on them.

* `ps()` now does not fail if both `user` and `after` are specified (#129).

# ps 1.7.0

* ps now compiles on platforms that enable OpenMP (#109).

* New functions `ps_get_cpu_affinity()` and `ps_set_cpu_affinity()` to query
  and set CPU affinity (#123).

* `ps_memory_info()` now does not mix up `rss` and `vms` on Linux.

* `ps_memory_info()` now reports memory in bytes instead of pages on Linux (#115)
