Copy multiple build artifacts matchin a name pattern.

Previously the compile command copied only the following artifacts:

  sketch.ino.hex (or .bin)
  sketch.ino.elf

now also the files matching the glob sketch.ino.*.hex will be copied.
This allows for some 3rd party core (like esp32) to copy also the extra
file sketch.ino.partitions.bin.

Should fix #163
