Release 1.3.0 - Better ESP32 partition support

This release rewrites the ESP32 partitions.csv support to allow for things like using "M" and "K" to specify partition sizes, as well as automatic sequential assignment of addresses. It also checks the partition type, not name, as well as recognizing littlefs type partitions.

RP2040 and RP2350 should see no differences.

What's Changed

• Redo ESP32 partitions.csv parsing by @earlephilhower in #62
• Calculate the fsEnd for ESP32 properly by @earlephilhower in #63
