Some minor cleanup.

• Swap log with slog.
• Warn when rate of sample consumption is less than configured sample rate.
• Adjusted how blocks are read and consumed. This may help with #321 and #327.
• Minimum toolchain version now 1.21.

Full Changelog: v0.9.4...v0.9.5

Opening os.DevNull on Windows broke in go1.24.

Bumping to fixed version.

Go module debug information test.

Cut away a lot of the fat in various buffers and implemented a protocol wrapper for R900 meters that transmit consumption as a hexadecimal coded digits. This also marks the first version which performs well enough to receive at full sample rate on an RPi2 without dropping any samples.

Changes:

• 2b386b0 Add R900 BCD Protocol (#58)
• 17b0016 Remove IQ buffer from decoder, implement buffer for sample dumping in main program.
• cedc2f8 Rename SCM test and update meters.csv
• 082d452 Maintain internal signal buffer since we trimmed the decoder-specific one.
• b567710 Resize Filter and csum buffers. Rename Pack to Transpose.
• 1c5bbb4 Simulation (#51)
• 2bee3a8 Rename recv.go to main.go
• 1742cc5 Fix length of bits to pack.
• 508c42c Remove old calculation from MagLUT.
• 1378c68 Remove Sqrt in MagLUT, sensitivity is unaffected. Use appropriate scaling in LUT calculation.
• faba109 Trim Signal and Filtered buffers to only necessary lengths.

Decimation was broken in the previous release when the new preamble search was implemented. This release fixes that bug.

Changes:

• 31bbf3f Use decimated packet configuration in preamble search. Fixes #47.
