[REQUEST] Silabs Zigbee EmberZNet 6.10.7.0 NCP firmware images

Silicon Labs EmberZNet version 6.10.7.0 is the latest bug-fix release in the 6.10 series so should be the latest stable in that series.

Like to ask to add/update all "B" images (e.i. images for EFR32MG2x like the EFR32MG21) from EmberZNet 6.10.3.0 to 6.10.7.0

ID #	Description
398694, 823888, 519731	ZCL reporting plugin is modified so that a rarely occurring exception condition (failure to read a reportable attribute's value; possibly because the attribute's endpoint is disabled) does not result in excess execution cycles, repetitive printing of a debug message, and (for an RTOS configuration) blocking of a lower-priority task.
841499	Fixed issue where a newly joined device can sometimes not get added to the child table if its IEEE address is not known.
1150905	Fixed spurious frame pending bit set when there is no data pending.

ID #	Description
1103581	Fixed an issue that caused a new device to join the network with a random extended PAN Id instead of using the same from received beacon. This difference in extended PAN Id was causing a PAN Id conflict upon device join.
