fix: #6

- Update `study.modality` and `dicomJson.00080061`
after storing the instance to Mongodb
- Fix the `ImagingStudy.modality` type
> The type is array of codingSchema
- Fix the `ImgagingStudy.endpoint` type
> The type is array of refSchema
> The line 453 in `postSTOW.js`
- Remove read value of 00080061 and set `study.modality`
in `DICOM2FHIRImagingStudy.js` file
> The 00080061 may not present in DICOM instance,
> it is calculate from DB and use for querying
- Remove calculate modalities in study when querying
> The value modalities in study is updated post storing
> It already in DB,
> we can send objects directly without calculating modalities in study
