Changed printing to use proper scientific notation

[ewu63]

Purpose

I changed a lot of the printing that used the format e. to use es., so that numbers show up as 4.9E2 instead of 0.49E3. I was really annoyed with the constant leading zero, so this should make everything more readable.

I used some regex to find these, so I might've missed some stuff. Would appreciate some checking by ADflow maintainers since I'm not as familiar with the code. This may also be a good time to change other printing formats, especially since I noticed we are now showing 16 decimal places which is probably too much.

Type of change

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (non-backwards-compatible fix or feature)
• Code style update (formatting, renaming)
• Refactoring (no functional changes, no API changes)
• Documentation update
• Maintenance update
• Other (please describe)

Testing

I ran the MACH-Aero tutorial and saw that the printing is now using proper scientific notation.

Checklist

• I have run flake8 and black to make sure the code adheres to PEP-8 and is consistently formatted
• I have run unit and regression tests which pass locally with my changes
• I have added new tests that prove my fix is effective or that my feature works
• I have added necessary documentation

@nwu63 I updated one more place that I was aware was missing. Think this is somewhat complete in terms of printout to the terminal.
Perhaps we should also consider updating how the slice/lift .dat files write to the files, as they also use the leading zero notation.

I agree, I've pushed up some more changes. Please take a look.

I tried this out locally and it is a definite improvement. I actually like 16 digits being printed for the monitor variables, so I am fine with this as is. I also checked that the Tecplot output files still work with the new format.
