[Bug] Upload with micronucleus fails with space in build path

[smlz]

Description Uploading a sketch fails, when there is a space character in the build path (e.g. a username containing a space, which is strangely allowed by Windows).

Only the part after the space character is subsequently used as file name for the hex file, and thus fails.

Here is an example output when uploading the Blink sketch to a Digispark board (see third last line):

Sketch uses 542 bytes (8%) of program storage space. Maximum is 6586 bytes.
Global variables use 6 bytes (1%) of dynamic memory, leaving 506 bytes for local variables. Maximum is 512 bytes.
