Contact limited to 350 MeshCore companion Heltec v4

[alecs13]

I have a Heltec V4 configured as a companion for MeshCore and I have just reached the limit number of contacts but I have plenty of memory left (I only used 7% of the available memory of the device)
Please remove the limit or make an option when configuring the companion to select maximum number of contacts

it is usually not needed to have more than 350 contacts - you are able to set auto-add to only "Chat Users" and set "Override oldest". To resolve repeater names from discover list, just choose "Use discover list" from upper right context menu when looking at "Heard repeats"

Note that we are unlikely to raise number of contacts from 350, because it occupies both RAM and flash and it would negatively impact devices with less RAM/flash, like nRF52 powered ones. If you still believe you need more contact slots, feel free to build firmware with MAX_CONTACTS set to higher number.
