Show candidate and sampling progress instead of raw sd-cli linesHEADmaster

The status line echoed sd-cli's latest log line. During the low-VRAM
retry that is a recovered [ERROR line, which reads like a crash and got
a working run interrupted. Show the candidate being sampled and its
sampling progress bar only.
