Unavailable character of "-" is not restricted on creating Qt for MCUs projects.

Errors occurred at build time if an MCU Application Project is created with "-" in the project name in QtCreator.
I think the reason is that the main program template uses the file name as it is when building the mcu project,
but it would be better for users to restrict unavailable characters by QtCreator.

Error messages(included Japanese):error_log.txt

Qt for MCUs version: 1.9, Windows

Steps to Reproduce(QtCreator):
select New File or Project
select Application(Qt for MCU)
input project name included "-", eg."test-mcu".
after the project settings, build and run.

Attached a sample project created following the steps:test-mcu.zip
