Feat 85: validate & format datetime in xlsx job template

[helen-m-lin]

closes #85

• Add data validator for acq_datetime column to check input is valid date
• Enforce excel to format and save dates in ISO datetime format (yyyy-mm-dd hh:mm:ss)
• Update unit tests and add new test for files with empty rows (Excel saves formatted blank cells as empty rows)

ISO format is typically represented at YYYY-MM-DDTHH:mm:ss although I'm not sure how excel does it

[helen-m-lin]

Both work in excel as custom formats and pass the regex check from BasicUploadJobConfigs._DATETIME_PATTERN1

I tried to match the ValueError raised in BasicUploadJobConfigs._parse_datetime and what we have in the sample csvs, but I'm happy to change it to YYYY-MM-DDTHH:mm:ss instead. What do you think?

	raise ValueError(
	"Incorrect datetime format, should be"
	" YYYY-MM-DD HH:mm:ss or MM/DD/YYYY I:MM:SS P"

[jtyoung84]

We should handle both the space and the 'T' but use the YYYY-MM-DDTHH:mm:ss for the XLSX_DATETIME_FORMAT if possible
