v0.6.1

Fixed a memory ownership issue in nrf_modem_init. The nrf_modem_init_params pointer given to the init must have a static lifetime. This has been a stack variable since forever.
Originally this seems to have not been required, but this changed +-4 years ago without documentation update from Nordic.

Release 0.6.0 (uses NCS 1.5.1)

• Updated to nrfxlib-sys v1.5.1.
  • Requires Rust v1.51 as we use the new resolver to allow bindgen as a build-dep
  • Rename FFI exports from bsd_X to nrf_modem_X
  • Implement IPC functionality
  • Implement library and transmit heaps
  • Supply hard-float libraries by default. The nRF9160 has an FPU so we might as well use the VFP registers.
• Update to latest heapless - no more heapless::consts::Uxx

v0.5.0

• Updates to latest nRF9160 PAC.
• Updated to nrfxlib-sys v1.2.0
  • Certificates now handled with AT commands rather than old nrf_inbuilt_key_write API.
• Now reports CME and CMS error codes
