This release:

• adds optional support by zeptoIPv4 and zeptoIPv6 for Multicast DNS, both for looking up hostnames over Multicast DNS and for assigning a hostname to one's device with Multicast DNS.
• optimizes multicore::test-set, used by slocks, to distribute usage of hardware spinlocks on the RP2040 and RP2350 across 16 spinlocks rather than only using one spinlock, reducing contention in multicore execution.
• adds optional support for ILI9341-based displays, which the PicoCalc terminal emulator supports in both graphical and text-only variants.
• adds friendlier zeptoIPv4 and zeptoIPv6-based applications that can be combined with one another.
• adds optional bitmap literals.
