drivers: sensor: max30101: Enhanced sample_fetch to match datasheet

The max30101 allows to configure time slots in samples acquisition.
It is now supported by adding matrix mapping for the slot/fifo
indexing. When a channel is present multiple times, the resulting
sample from the `sensor_channel_get` is averaging each entry.
Added Die temperature sample acquisition with
`CONFIG_MAX30101_DIS_TEMPERATURE` Kconfig.
