Update file cache logic

[sambles]

Issue Description

The file caching in the OasisDataManager package is based on the filename rather than the hash of the file data.
This causes a problem with filenames like analysis_1_inputs.tar.gz which is the input tar (oasis files)

Example

1. Generate inputs With loc_file = A --> File stored analysis_1_inputs.tar.gz
2. Run Generate Losses loc_file = A --> File cached analysis_1_inputs.tar.gz
3. Update portfolio with loc_file = B
4. Generate inputs With loc_file = B --> File overwritten with same name analysis_1_inputs.tar.gz
5. Generate Losses:

run_analysis[8fa67556-5a22-4c79-885c-d78f7c4c90d7]: {'oasislmf': '2.3.4', 'ktools': 'fmcalc : version: 3.12.2 - git update: ', 'platform': '2.3.4'}
[2024-05-02 09:12:49,079: INFO/ForkPoolWorker-1] Get from Cache: oasis/server/analysis_1_inputs.tar.gz

(This is the original analysis_1_inputs.tar.gz Tar file from Step 1

Workaround to prevent the above from happening: OasisLMF/OasisPlatform#1037

However, still might be an issue with filenames we don't have control over (like model data)
