[FEAT-API]: Create Hydrograph Manipulation h5 Upload handler

[martyheynbah]

Create handlers specifically for uploading (POST) h5 files.

• We want users to be able to upload multiple h5 files at once
• when h5 files are uploaded we want to add logic to add correlating data (File type: "Water Level" or "Wave", and filename) to existing relevant database tables based off data in h5 filename.
  • match savepoint_id in filename to relevant savepoint
  • type should be in the filename as well
