Use lower case names for split values

[cfezequiel]

Is your feature request related to a problem? Please describe.
Change split values from all caps to lower case.
This makes file/directory naming more consistent with the split.

Describe the solution you'd like
TRAIN -> train
VALIDATION -> validation
TEST -> test

Describe alternatives you've considered

1. No change

• There's a bit of skew when it comes to mapping split value with file/dir name.

Hi @AnshuTrivedi , thanks for the comment, and apologies for the delay in response. It seems I wasn't getting any notifications for non-PR comments in this repo (should be fixed now).
Regarding this issue, the idea is to change the dataset split values that the tool uses from 'TRAIN', 'VALIDATION', 'TEST' to 'train', 'validation', 'test'. This would affect the following:

Input CSV/Pandas DataFrame: the split column should have train, 'validation', 'test' as acceptable values
Input image directory: the image directory should now have the following structure

train/
  label0/
    image00
    ...
  label1/
  ...
validation/
  label0/
     ...
  ...
test/
  label0/
  ...

It's basically a cosmetic change.
Let us know if you want to take this on.
