Fixes BrainJS#948 Initialize the `equations` property in the `LSTM` class constructor in `src/recurrent/lstm.ts`. * Ensure the `equations` property is properly populated before it is accessed in the `get` method of the `LSTM` class. * Initialize the `equations` property in the `LSTMTimeStep` class constructor in `src/recurrent/lstm-time-step.ts`. * Ensure the `equations` property is properly populated before it is accessed in the `getEquation` method of the `LSTMTimeStep` class. * Add test cases in `src/recurrent/lstm-time-step.test.ts` to verify that the `equations` property is properly initialized and populated. * Add end-to-end test cases in `src/recurrent/lstm-time-step.end-to-end.test.ts` to verify that the LSTM model correctly trains and produces the expected output values.

The error is this:
brain-browser.js:41191 Uncaught TypeError: Cannot read properties of null (reading 'equations')
at LSTM.get (brain-browser.js:41191:22)
at LSTM.run (brain-browser.js:40778:17)
at perceptron.html:37:16
And my code is this:

So, i want all inputs get the same value at each row.
