file permissions follow system umask even if explicitly set

[vitoyucepi]

Describe the bug
All file functions follow umask even if explicitly set permissions in function calls.

To Reproduce

file.mkdir(perms=0o777, '/tmp/1')
file.write(data='test', perms=0o777, '/tmp/2')
output.file(perm=0o777, %opus, '/tmp/3', blank())

Expected behavior
If the perm-like parameter is explicitly set, then umask should be overridden.
Add the umask set function.

Version details

• OS: ubuntu:22.04 in docker

Thanks for reporting. I added umask getter/setter, following the settings convention:

# Get current umask:
umask()

# Set current umask:
umask.set(...)

# Equivalent to in `main`/2.2:
umask := ...
