Hello,

I noticed that the hospital admissions data is now split between 4 files:

Weekly Admissions and Beds up to 6 April 2021 (XLSX, 4.0MB)
Weekly Admissions and Beds from 7 April up to 30 September 2021 (XLSX, 2.6MB)
Weekly Admissions and Beds from 1 October 2021 up to 31 March 2022 (XLSX, 2.6MB)
Weekly Admissions and Beds 11 August 2022 (XLSX, 1.9MB)

Could you please update download_trust_data to include this?

Thank you!
