Finally convince the compiler to store the text strings into flash. Saves approx 2k of Global ram, for a trade-off of between ~0-0.5k of extra flash space used. e.g. _(updated)_ * IRMQTTServer example code: - Before: RAM: [===== ] 54.1% (used 44344 bytes from 81920 bytes) Flash: [===== ] 54.2% (used 566209 bytes from 1044464 bytes) Bin file size = 570368 - After: RAM: [===== ] 51.3% (used 41992 bytes from 81920 bytes) Flash: [===== ] 54.2% (used 566201 bytes from 1044464 bytes) Bin file size = 570352 * IRrecvDumpV2 example code: - Before: RAM: [==== ] 37.9% (used 31044 bytes from 81920 bytes) Flash: [==== ] 35.6% (used 372025 bytes from 1044464 bytes) Bin file size = 376176 - After: RAM: [==== ] 35.5% (used 29072 bytes from 81920 bytes) Flash: [==== ] 35.7% (used 372525 bytes from 1044464 bytes) Bin file size = 376672 Fixes #1614 Fixes #1493 Co-authored with @mcspr
