Describe the bug
Attempting to load Rinex OBS file results in crash

To Reproduce

1. create and activate a new VENV:
   (base) sjbespa@mbp-et envs % python -m venv ./gnss_lib_py
   (base) sjbespa@mbp-et ~ % source /opt/miniforge3/envs/gnss_lib_py/bin/activate
2. Install gnss_lib_py
   (gnss_lib_py) (base) sjbespa@mbp-et ~ % pip install gnss_lib_py
3. load an obs file
   (gnss_lib_py) (base) sjbespa@mbp-et ~ % python

import gnss_lib_py as glp
rinex_obs = glp.RinexObs("/Users/sjbespa/Desktop/pie1015/pie10150.26o")

4. Result:
   [numerous FutureWarnings deleted]
   numpy.exceptions.DTypePromotionError: The DType <class 'numpy.dtypes.Float64DType'> could not be promoted by <class 'numpy.dtypes.DateTime64DType'>. This means that no common DType exists for the given inputs. For example they cannot be stored in a single array unless the dtype is object. The full list of DTypes is: (<class 'numpy.dtypes.Float64DType'>, <class 'numpy.dtypes.DateTime64DType'>)

Expected behavior
