Typo in C_n_numu

[cgiovanetti]

C_n_numu in thermo has a stray T_nue where it should have a T_numt:

    C_n_numu = 8 * f_n * const.GF**2 / jnp.pi**5 * (
        4 * (gmuL**2 + gmuR**2) 
        * (T_g**8 - T_nue**8 * jnp.exp(2 * mu_numt / T_numt))
        - (
            T_numt**8 * jnp.exp(2 * mu_numt / T_numt) 
            - T_nue**8 * jnp.exp(2 * mu_nue / T_nue)
        )
    ) / const.hbar

should instead be

    C_n_numu = 8 * f_n * const.GF**2 / jnp.pi**5 * (
        4 * (gmuL**2 + gmuR**2) 
        * (T_g**8 - T_numt**8 * jnp.exp(2 * mu_numt / T_numt))
        - (
            T_numt**8 * jnp.exp(2 * mu_numt / T_numt) 
            - T_nue**8 * jnp.exp(2 * mu_nue / T_nue)
        )
    ) / const.hbar
