What's Changed

• Fix link to libvolk install page by @argilo in #44
• Remove NaNs and process hanging by @jj1bdx in #45

Changes in details

• 20231215-0: Fix the following known bugs and refactor the code to streamline the functioning:
  • Bug: a hung process during the startup period before valid audio signals are coming out
  • Bug: displaying -nan in the output level meter in broadcast FM and NBFM
    • The NaN is presumably generated by volk_32fc_s32f_atan2_32f() in PhaseDiscriminator::process()
    • This NaN issue was presumably the root cause of the multipath filter anomaly first fixed in 20231213-1
  • Enhancement: streamlining processing flow in the main for loop of main()
  • Enhancement: removing the initial waiting period for startup; the output is now activated from the block number 1
  • Utility addition: adding Utility::remove_nans(), a function to check and substitute NaNs and infinity values in IQSamplesDecodedVector
