 *.cs16 - Complex 16-bit signed integer (BladeRF)
 *.cs8 - Complex 8-bit signed integer (HackRF)
 *.cu8 - Complex 8-bit unsigned integer (RTL-SDR)
 *.f32 - Real 32-bit floating point samples
 *.f64 - Real 64-bit floating point samples (MATLAB)
 *.s16 - Real 16-bit signed integer samples
 *.s8 - Real 8-bit signed integer samples
 *.u8 - Real 8-bit unsigned integer samples

 * Large (100GB+) file support
