This regex would only look at the .text section, but the .data section (initialization values for global variables) also takes up space in flash. The regex is changed to match both sections. arduino-builder will then add together the values and show the sum to the user (this summing seems to have been supported at least since the introduction of arduino-builder, see: arduino/arduino-builder@0802e27 The regex format is copied from the AVR core, which already did the same (though AVR also includes a .bootloader section, which is not relevant here it seems, any bootloader is included in .text). This also copies the start-of-line ^ anchor to the regex, making the matching more accurate.
This was previously omitted, causing arduino-builder to not report the amount of RAM used. This adds the regex, based on the regex used by AVR (omitting the .noinit section, which is not supported by the SAMD linker scripts).

This fixes the size regex to include intitialized variables (
.datasection) and adds a data/RAM size regex, allowing the RAM usage to be displayed.
