Subject: [PATCH 1/2] feat(esp_https_ota): Skipped read_header and write for
 custom partition

- For custom partition less than IMAGE_HEADER_SIZE (1024 bytes), give
error - 'complete header not received'
- Skipped the read_header function for custom partition, and directly
jumped to IN_PROGRESS state

Subject: [PATCH 2/2] feat(partition_ota): Modified pytest for storage data

- Modified test for storage data, reduced the size to 500 bytes,
less than IMAGE_HEADER_SIZE (1024), to check the workflow, if the
custom partition other than APP and BOOTLOADER less IMAGE_HEADER_SIZE
performed OTA
