Deprecation warning for `date_parser` in Pandas `read_csv` function.

I currently encounter a deprecation warning when using the pd.read_csv function with date_parser.

FutureWarning: The argument 'date_parser' is deprecated and will be removed in a future version. Please use 'date_format' instead, or read your data in as 'object' dtype and then call 'to_datetime'.

this is supported by the Pandas documentation, which states:

Deprecated since version 2.0.0: Use date_format instead, or read in as object and then apply to_datetime() as-needed.

this warning was obtained whilst running the following line of code:

simfin/simfin/load.py

Lines 154 to 155 in 413ec16

	df = pd.read_csv(path, sep=';', header=0,
	parse_dates=parse_dates, date_parser=date_parser)

as per the warning and the supporting Pandas documentation, I'm recommending that we read data in as object dtype and then call pd.to_datetime() to convert each of these columns from object dtype to datetime64[ns] dtype.

I've submitted a pull request here.

I'm getting the same warning:
"/opt/anaconda3/lib/python3.12/site-packages/simfin/load.py:154: FutureWarning: The argument 'date_parser' is deprecated and will be removed in a future version. Please use 'date_format' instead, or read your data in as 'object' dtype and then call 'to_datetime'.
df = pd.read_csv(path, sep=';', header=0,"

Looks like this got fixed in v1.0.2 (April 2026), load.py doesn't use date_parser anymore, it lets pandas parse the ISO date strings directly. Might be worth closing this one out.
