* pcap: reuse Frame memory
* slog: reduce heap allocations of addresses; also prevent heap alloc of dhcp options in pcap
* dns: heapless improvement; add StackAsync buffer for more heapless operation; start thinking of errors
* errors: begin standardise errors in lneto
* errors: finish standardization of errors
* fix merge issues
* add more lneto errors to rest of package
* format errors.go
* reduce heap allocations in tcp logging; omit use of AppendFloat which allocates a metric sh*tton
* debugheaplog: better heap statistic logging
* heap: use string for pcap.Frame.Protocol
* add potential to eliminate Flags.String heap alloc, remove incorrect HEAP comments
* add StackAsync.DebugErr and httpraw.SetBytes
* many heap alloc reductions and replacement of bytes.Equal with internal.BytesEqual
* pcap: reuse Frame memory
* slog: reduce heap allocations of addresses; also prevent heap alloc of dhcp options in pcap
* dns: heapless improvement; add StackAsync buffer for more heapless operation; start thinking of errors
* reuse function for reclaiming frames among all protocols for lower memory usage
* remove extraneous code
* tcp: mss honoring; accept syn with ECE/CWR flags; add RSTQueue type
* tcp: move option logic to own file
* remove prints in pcap
* add MSS send threshold inspired by linux/freebsd/lwip thresh
* claude suggests a way forward
* add timing to capture printer
* add pcap.Flags
* fix ICMP CRC calculation and add test
* bugfix: still send data on half-close state(close-wait)
* fix pcap test
* improvements to dhcpv4 server
* begin adding examples/httpserver
* add better VLAN tagging methods
* pcap: add error printing; fix bug in CRC
* ipv4: ToS and Flags construction and flag manipulation improvements
* add dhcp interception to httptap and improve httpserver example
* Simplified checksum calculation and verification
* Fixed tests
* UDP: using NewBoundedFrame to create a Frame instance limited to the actual frame size.
* Minor: renamed some functions
* Commented and made more readable consecutive SetCRC calls.
* Fixed icmp checksum calculation after rebase
* Replaced NewBoundedFrame with explicit validation
* Checksum 0x0000 is returned as 0xFFFF (mandatory for UDP, common for TCP)
* Both checksum zero values (0x0000 and 0xFFFF) are accepted when receiving
* Rename parameter in VerifySum16 to expectedSum16
