Support TARGET_SEEED_XIAO_NRF52840_SENSE_PLUS

[j-era]

Please update this lib so we can use the IMU on the Sense Plus.

1. You need this commit 9a2c4e656f9ac943cf3a00f31a7c787d84aeb51a
2. Using this commit there is another check missing:

#if defined(TARGET_SEEED_XIAO_NRF52840_SENSE) || defined(TARGET_SEEED_XIAO_NRF52840_SENSE_PLUS)
    NRF_P1->PIN_CNF[8] = ((uint32_t)NRF_GPIO_PIN_DIR_OUTPUT << GPIO_PIN_CNF_DIR_Pos) | ((uint32_t)NRF_GPIO_PIN_INPUT_DISCONNECT << GPIO_PIN_CNF_INPUT_Pos) | ((uint32_t)NRF_GPIO_PIN_NOPULL << GPIO_PIN_CNF_PULL_Pos) | ((uint32_t)NRF_GPIO_PIN_H0H1 << GPIO_PIN_CNF_DRIVE_Pos) | ((uint32_t)NRF_GPIO_PIN_NOSENSE << GPIO_PIN_CNF_SENSE_Pos);
#endif
