mrgsolve 1.5.0

• New functions mwrite_yaml() and mwrite_cpp() can write a model object back
  to a file, accounting for all updates since the model was read from native
  mrgsolve format using mread() (#1213).

• New function mread_yaml() for reading back models written out with
  mwrite_yaml() (#1213).

• New functions in evtools plugin: evt::replace() works like evt::bolus(),
  but will replace the amount in a given compartment rather than add to it
  (#1203).

• The nm-vars plugin now exposes DEXP(), LOG10(), COS() and SIN()
  for use in the mrgsolve C++ code blocks (#1199).

• An error is now generated when KA is equal to CL/VC while simulating from
  the one-compartment model with analytical solution invoked through
  $PKMODEL (#1179, #1197).

Bugs Fixed

• A bug was fixed when certain data frame inputs were passed to as_data_set()
  (#1115, #1196).
