AUX should not be used as name of file or directory as it is reserved name in Windows

[kacperrzepecki]

Hi,
You have two folders named "aux":

• lib/src/daily/aux
• test/aux

aux is reserved word in Windows and should not be used as name of a file or directory.
https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file?redirectedfrom=MSDN

Do not use the following reserved names for the name of a file:

CON, PRN, AUX, NUL, COM0, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, COM¹, COM², COM³, LPT0, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9, LPT¹, LPT², and LPT³. Also avoid these names followed immediately by an extension; for example, NUL.txt and NUL.tar.gz are both equivalent to NUL.

Here is more explanation on why that is the case:

Impact:

1. At the moment the repository cannot be checked out on windows:

C:\gitrepos>git clone https://github.com/ivofernandes/yahoo_finance_data_reader.git
Cloning into 'yahoo_finance_data_reader'...

You can inspect what was checked out with 'git status'
and retry with 'git restore --source=HEAD :/'

2. It also causes pub get to fail as reported here, however this one seems to work at least on some windows environments - I am a bit unsure if this is 100% related
