`filewriter`: static metadata

先找出 filewriter 及其對 runStart/runStop 訊息的處理方式，然後比較現有檔案寫入中繼資料的方式。實作對所列靜態中繼資料的支援，包括將可執行檔名稱用於 program_name，並確認 runStart 和 runStop 中可用的所有值都已寫入。

The filewriter must be able to write the 'static' metadata for a run.

These are pieces of metadata which only require knowledge of the runStart and runStop messages. This assumes that the run start is emitted with appropriate metadata to enable this data to be written.

This includes:

• raw_data_1/beamline
• raw_data_1/definition
• raw_data_1/definition_local
• raw_data_1/duration
• raw_data_1/end_time
• raw_data_1/experiment_identifier (RB number)
• raw_data_1/measurement/first_run
• raw_data_1/measurement/id
• raw_data_1/measurement/label
• raw_data_1/measurement/subid
• raw_data_1/measurement/type
• raw_data_1/measurement_first_run
• raw_data_1/measurement_id
• raw_data_1/measurement_label
• raw_data_1/measurement_subid
• raw_data_1/measurement_type
• raw_data_1/name
• raw_data_1/notes
• raw_data_1/program_name
• raw_data_1/run_cycle
• raw_data_1/run_number
• raw_data_1/sample/distance
• raw_data_1/sample/height
• raw_data_1/sample/id
• raw_data_1/sample/name
• raw_data_1/sample/shape

• raw_data_1/user_1/name

Potential differences from existing files

• program_name will no longer be ISISICP.exe and will be the name of the filewriter executable.
