arbitrary-int vs bitbybit vs ux

Modern and lightweight implementation of u2, u3, u4, ..., u127.

Efficient implementation of bit-fields where several numbers are packed within a larger number and bit-enums. Useful for drivers, so it works in no_std environments

Implement the following non standard integers: u2, u3, u4, u5, u6, u7, u9, u10, u11, u12, u13, u14, u15, u17, u18, u19, u20, u21, u22, u23, u24, u25, u26, u27, u28, u29, u30, u31, u33, u34, u35, u36, u37, u38, u39, u40, u41, u42, u43, u44, u45, u46, u47, u48, u49, u50, u51, u52, u53, u54, u55, u56, u57, u58, u59, u60, u61, u62, u63, i2, i3, i4, i5, i6, i7, i9, i10, i11, i12, i13, i14, i15, i17, i18, i19, i20, i21, i22, i23, i24, i25, i26, i27, i28, i29, i30, i31, i33, i34, i35, i36, i37, i38, i39, i40, i41, i42, i43, i44, i45, i46, i47, i48, i49, i50, i51, i52, i53, i54, i55, i56, i57, i58, i59, i60, i61, i62, i63
